Abstract: 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.

Abstract: A method and apparatus for correcting direct current (DC) offset errors of a received signal in a direct conversion receiver (DCR) are provided. DC offset correction algorithms are incorporated into the DCR, each algorithm being optimized for a particular receive signal operating environment. The DC offset correction algorithms remove DC offset errors in baseband In-phase and Quadrature-phase signals received within the direct conversion receiver baseband signal path. Individual DC offset correction algorithms are selected for use as determined by a signal quality estimator component. A DC offset correction component of the direct conversion receiver determines an appropriate DC offset correction algorithm suited for a particular operating environment. A criterion for a signal quality estimate is set to control transitioning between DCOC algorithms. A dual threshold strategy may be adopted to transition between one DC offset correction algorithm and another DC offset correction algorithm to provide hysteresis.

Abstract: A method for maximizing intermodulation interference protection during a handoff between radio cell sites (300) includes scanning a plurality of radio channels (302) and measuring the signal power (307, 315) for at least one of the radio channels. One or more receiver attenuators (313) are then set based on the detection of intermodulation (IM) interference of the measured channel. The attenuators are then scaled (311) based on the degree of IM interference. If the attenuators cannot mitigate this interference below some predetermined level, the radio channel is changed (321) and the process begins again to ensure a high quality of communication with a cell site.

Abstract: A subscriber (1001) provides a cumulative adjustment value in memory. Upon transmission of the inbound signal to a base station (102), the subscriber (1001) receives a relative adjustment value. The base station (102) calculates the relative adjustment value based on receipt of the inbound signal against a time window. The subscriber (1001) sums the adjustment value with the cumulative adjustment value to create a new cumulative adjustment value. The subscriber (1001) stores the new cumulative adjustment value in memory, and a subsequent inbound signal is transmitted using the new cumulative adjustment value. Alternatively, the subscriber (1001) obtains a priori information as to when a base station (102) transmits a burst. Upon receipt of the burst, the subscriber (1001) calculates a time delay between when the burst was transmitted and when the burst was received. The subscriber (1001) stores the time delay, and advances the transmission timing by the time delay.

Abstract: A method for the selection of forward error correction (FEC)/ constellation pairings (800) for digital transmitted segments based on learning radio link adaptation (RLA) including formatting a packet transmission having a predetermined number of information bits (801). The packet is then split into a plurality of segments (803) where an RLA is used (805) to determine the optimum format of the packet. The plurality of segments is then sent to a channel encoder for FEC encoding and symbol mapping (807) at a rate selected by the RLA. The segments are then formatted into packet blocks (809) and transmitted in blocks that form a time slot at a constant symbol rate.
