A receiver implemented decoding of selectively processing channel state metrics to minimize power consumption and reduce computational complexity. The method involves disabling a channel state (signal strength) computation algorithm during decoding of information received on the control channel of a trunked communication system during static conditions. Because the bulk of a radio's power is consumed while in standby mode listening to data information transmitted over a control channel, and because control channel information is typically received while in a good channel quality environment, significant power consumption reduction is realized by disabling the channel state computation algorithm. When a poor quality channel condition is detected, such as may occur when a message error rate (MER) is above the MER quality threshold set for that radio, the radio will enable the channel state computation algorithm.

Methods of enabling late entry into an on-going spread spectrum call are described. A late join frame replaces, and has the same size as, a traffic frame. A late join slot in the late join frame contains sufficient information in preamble and sync subframes to permit a target to join the call. The traffic slots in the late join frame replicate data such that call quality of the call is substantially unaffected if one of the remaining traffic frames is not received. The preamble and sync subframes frequencies may be the same as, or different from, preamble and sync frames frequencies during a call establishment phase of the call. If different, the preamble and sync subframes frequencies are selected from one or more frequencies. Use of the preamble and sync subframes frequencies is compensated for when selecting the traffic slot frequencies to obtain uniform utilization of the spectrum.

A radio device requires a tunable transceiver such that the transceiver can be accurately set to a desired frequency. When a signal with known frequency accuracy is being received, an offset detector can determine the frequency offset generated by the transceiver due to improper tuning. An automatic frequency control (AFC) system (100) is comprised of a tunable transceiver, an offset detector (103) and an AFC control processor (105) for utilizing information from the offset detector to reduce the inaccuracy in frequency by tuning the transceiver towards the received signal frequency. The AFC control processor (105) utilizes one of more threshold levels for defining a maximum correction threshold (311) based upon the desired maximum offset correction. These thresholds are used by the AFC control processor (105) to efficiently control the predetermined frequency range of the tunable transceiver (101) for most efficient operation.

Briefly, according to the invention, a receiver (100) for receiving and decoding a carder signal is described. A carrier signal is modulated with an information signal which has one of a plurality of formats. The receiver includes a circuit (104) for receiving and demodulating the carrier signal to produce a demodulated signal. The receiver (100) also includes a digital signal processing subsystem (108) for calculating the correlation function of the demodulated signal and based on this correlation function classifies the format of the demodulated signal. A decoder (118) is further included in the receiver (100) to decode the demodulated signal once it has been classified.

A communication device receives control information during transmission of streaming data, such as speech data, over a wireless channel (300). The communication device identifies a portion of the streaming data, such as representing a pause in speech, as compressible data or white space data (310, 320). Continuous transmission of the streaming data is interrupted to request and receive control information on the wireless channel, using the channel space made available by not transmitting the identified portion of data or by transmitting it in a more compressed format (330, 340).

A method for correcting I/Q imbalance in a received signal is disclosed. The method includes the steps of grouping () the received signal into a predetermined number of clusters, and determining () at least one coefficient value by feeding the predetermined number of clusters into a nested loop. The method further includes computing () a compensation value based on the at least one coefficient value, and correcting () the I/Q imbalance in the received signal by using the compensation value.

An adaptive dc compensation technique () eliminates dc error for both digital and constant envelope modulation protocols (). For analog modulation, a dc averaging technique utilizes piece-wise continuous dc averaging () that calculates discrete dc error values over a variable number of samples () and updates the dc compensation value as a fixed value for a specified sample length (). The piece-wise “update-and-hold” technique () results in a pseudo high pass filter response with an equivalent corner. For digital modulation, a continuous high pass filter section of the receiver is enabled ().

A method of detecting an on-channel signal and synchronizing signal detection with correcting for DC offset errors in a direct conversion receiver is presented. A received signal is digitized, and a state machine operates to detect the presence of an on-channel signal. If the signal is not detected, a mixed mode training sequence is initiated in which the DC offset errors in both an analog and digital received signal path are corrected. While training, processing of the digitized samples by a digital signal processor and a host controller is suspended (while they are put into battery save mode) and the gain provided to subsequently received signals is minimized. The DC offset correction circuitry is bypassed and put into battery save mode at predetermined periods when DC offset correction is not performed.
