A communications system central controller which regulates the access of a plurality of remote units to a single communications channel is disclosed. The central controller establishes a period of time wherein a remote unit may request service following the transmission of another remote unit. The central controller interprets the remote unit request for service, stores the request, and grants permission for the remote unit to transmit its message in accordance with the priority in the storage means. The grant of service is revoked by the central controller after a predetermined period of time following the conclusion of the remote unit transmission.

A multi-channel transmitter (200) in accordance with the present invention overcomes the disadvantages of applying adaptive antenna array technology to multi-channel communication systems. The multi-channel transmitter includes a channel processing element (210), a plurality of radio frequency processing elements (206), and an antenna array (102). The channel processing element includes a channel processor adapted to receive a communication signal from a communication network, a splitter (216) coupled to an output of the channel processor for producing a plurality of substantially identical processed digital communication signal outputs. A plurality of gain and phase adjusters (214) in the channel processing element are coupled to the substantially identical processed digital communication signal outputs. An output of each phase and gain adjuster (214) is coupled to a plurality of up-converters (212), which each produce a digital intermediate frequency output. The plurality of radio frequency processing elements (206) are each coupled to an output of the digital up-converters (212).

A split frequency band signal digitizer (10) includes a first mixer (18) for translating a split-band signal (200) about a multiple of the sampling frequency. The split-band signal so translated is then communicated to an analog-to-digital converter (26). The digitized signal is then analyzed to recover an original portion of the split-band signal and a second portion of the signal aliased into a single Nyquist band.

A multi-channel digital transceiver (400) receives uplink radio frequency signals and converts these signals to digital intermediate frequency signals. Digital signal processing, including a digital converter module (426), is employed to select digital intermediate frequency signals received at a plurality of antennas (412) and to convert these signals to baseband signals. The baseband signals are processed to recover a communication channel therefrom. Downlink baseband signals are also processed and digital signal processing within the digital converter module (426) up converters and modulates the downlink baseband signals to digital intermediate frequency signals. The digital intermediate frequency signals are converted to analog radio frequency signals, amplified and radiated from transmit antennas (420).

The addition and removal of a dither signal takes place by generation of a first signal (102) and a second signal (104) by a first signal source (151) and a second signal source (152). A dither generator (103) is provided that generates a dither signal (106) that is added to the first signal (102) and subtracted from the second signal (104). The first signal (102) with dither added, and the second signal (104) with dither subtracted enter respective Digital to Analog Converters (DACs) (109, 111) and are converted to analog signal equivalents. Finally, the respective analog signal equivalents are summed together to form a composite signal with the dither signal (106) substantially eliminated.

A communication system which controls access to a single communications channel by a plurality of remote units arranged in predetermined groups is disclosed. Assignment of the channel is controlled by a central control station which provides time periods on the channel for remote units to request permission to transmit on the channel. As the channel becomes clear, the central control station transmits a grant of service to a requesting remote unit group permitting real time transmission of voice or data on the channel. At the conclusion of the transmission, the central control station detects an end-of-transmission condition and revokes the grant of service to the served remote unit group.
