A first remote vocoder receives analog voice and produces packetized vocoder data which is transmitted over a wireless link. A first local vocoder receives the packetized vocoder data from the wireless link. The first local vocoder converts the packetized data to a multibit PCM output. The first local vocoder also adds a detection code to one of the least significant bits (LSB) of the PCM output. The first local vocoder passes the PCM signal to the PSTN from the second end user. The first local vocoder also receives PCM input over the PSTN. The first local vocoder constantly monitors the least significant bit of the PCM input for a detection code indicating that a second local vocoder is connected at the receiving end. If the first local vocoder detects the detection code from the second local vocoder, it begins to substitute packetized data and a redundancy check for a second one of the LSB's of the outgoing PCM. The first local vocoder also begins to monitor the second one of the LSB's of the incoming PCM.

A modulator for a spread spectrum telecommunication system not only receives local data and processes it, but also receives input data from one or more other modulators, sums the input data with the local data, and provides the sum as data for a subsequent modulator or as final output for a transmit power amplifier. The modulator includes an input block and an output block and, depending on a control data signal, input data will be summed with the internally generated local data of the modulator before being provided to the output block. The output data can include parity data. The parity data can be used to check for faults such as might be introduced, for example, by a faulty connection or broken hard-wired interconnect. If an error is detected, the summation function of the transmit modulator can be automatically disabled.

A packet switching architecture provides for a switch system comprised of a cellular base station in communication with the PSTN through a switch. Data packets are routed through the switch system as necessary to effect communication between the public switched telephone network (PSTN) and mobile radiotelephones disposed within the cellular coverage area surrounding the base station. A packet interconnection subsystem operates to transfer data packets between a plurality of interface ports, to which are coupled a corresponding plurality of signal lines. Within the interconnection subsystem, one or more distribution/consolidation (DISCO) interface units are mutually coupled together through a central router unit. Each DISCO interface unit is configured to consolidate the data packets received through at least two signal ports onto a consolidation bus, as well as to distribute the addressed data packets from a distribution bus to two or more of ports. In a preferred implementation, the interconnection subsystem is realized so as to efficiently provide redundancy among the interface units within the interconnection network.

A method and system for providing a reliable means to perform handoff from a code division multiple access (CDMA) system using a pilot signal to an alternative access communication technique system. Simple pilot box circuitry is added to a set of border base stations. The border base stations are base stations which operate only in the alternative access communication technique and which have coverage areas which are contiguous with coverage areas of CDMA operation base stations. The mobile unit monitors for the pilot signal from the border base stations in the same manner as it monitors for pilot signals from the CDMA operation base stations. When the mobile unit detects the pilot signal corresponding to a border base station, it notifies a system controller in accordance with standard operation. The system controller is aware that the pilot signal corresponds to a border base station and thus triggers a hard handoff process to the alternative access communication technique system in response thereto.

When one vocoding system is coupled to another vocoding system, a tandem arrangement results. The tandem configuration results in voice quality degradation as speech is encoded and decoded, then encoded and decoded again. One reason for the degradation is that postfiltering performed at the output of the speech decoding process introduces distortions in the spectral content of the reconstructed speech as compared to the original speech. The present invention prevents the degradation due to the use of postfilters by modifying the postfiltering within the vocoders where a tandem configuration exists. A detection code is embedded within the data signal to indicate the existence of a tandem configuration. If the detection code is received at a vocoder, modified vocoding is established within the vocoders to prevent the degradation due to the postfiltering.

An apparatus and method for adding and removing a target base station from a network of base stations, which includes base stations adjacent the target base station. The apparatus is comprised of two attenuators: a first for setting an artificial receive noise power level and a second for setting a transmit level. The transmit level determines the forward link coverage area of the base station. The artificial noise level sets the reverse link coverage area of the base station when a base station is added, initially the transmit power is low and the artificial receive noise power is high such that the forward and reverse kink coverage areas are collocated in close proximity to the base station. As the base station blossoms into full operation, the artificial receive noise power is decreased and the transmit level is increased such that the two coverage areas of the base station remain balanced as the coverage areas expand. When a base station is to be removed from a system, the same attenuators are used to wilt the two coverage areas in unison as the power level transmitted from the base station decreases.

The present invention is a method and apparatus for integrating a personal communication system with a cable television plant. A set of radio antenna devices (RAD) are connected to the cable plant. The RADs provide frequency conversion and power control of signal received from the cable plant for wireless transmission to the remote units. The RADs also provide power control and frequency conversion of wireless signals received from the remote units for transmission by the RADs onto the cable plant. In addition to the functions of standard base stations and centralized controller, the CATV base station must also compensate for gain variations in the cable plant. The downstream power control is regulated by a RAD reference signal which can be hidden within the CDMA signal for maximum efficiency. The upstream power control is regulated by an upstream gain reference signal which is individually transmitted by each RAD on the upstream link.

Techniques to improve the acquisition process in a spread spectrum environment. The signals from different CDMA systems are spread with different sets of PN sequences, with the PN sequences in each set being uncorrelated to the PN sequences in the other sets. The mobile station can attempt to acquire the pilot signal by processing the received signal with a first set of PN sequences corresponding to a first hypothesis of the particular signal being acquired. If acquisition of the pilot signal fails, a second set of PN sequences corresponding to a second hypothesis is selected and used to process the received signal. The PN sequences in the second set are uncorrelated to the PN sequences in the first set.

A novel and improved method and apparatus for generating a reduced peak amplitude high data rate channel comprised of a set of lower rate channels is described. The set of lower rate channels are phase rotated before being summed and transmitted. The amount of phase rotation is dependent on the number of channels used to form the higher rate channel. In an embodiment where two lower rate channels are used, the in-phase and quadrature-phase components of the two channels are complex multiplied before upconversion with an in-phase and quadrature-phase sinusoids. For a high rate channel comprised of more than two lower rate channels, the in-phase and quadrature-phase component of each channel is upconverted with a set of sinusoids that are phase offset from one another.

A method and apparatus providing softer handoff of a mobile unit between sectors of a common base station. A sectorized base station comprises a set of demodulation elements. Each demodulation element may be assigned to a signal from one of a plurality of sectors. The output of the demodulators are combined before the decoding process independent of the sector from which the data originated. This configuration provides improved output data reliability, more stable power control, and more efficient use of resources at the base station.
