Abstract: A system and method for minimizing inter-communications system mobile-to-mobile station interference includes a plurality of base stations (BS A and BS B) and a plurality of mobile stations (MS A and MS B) each communicating with a base station using a first mode of communication. A first mobile station (MS A) sends a message using a second mode of communication upon detecting interference with another mobile station (MS B) to determine the source of the interference. Once determined, the first mobile station (MS A) communicates with its base station (BS A) which, in turn, communicates with the second mobile station's base station (BS B) using a back haul network. The second mobile station's base station (BS B) may then instruct the second mobile station (MS B) to alter its transmission characteristics based upon instructions from the second base station (BS B) in order to reduce interference and improve overall communications quality.

Abstract: A receiver circuit (400, 500) receives a spread spectrum communication signal, such as a DS-CDMA signal, including a pilot channel and including a power control designator. The signal is despread and decoded. The pilot symbols on the pilot channel are provided to a channel estimator (408) for estimating the channel phase and channel gain of the communication channel. This estimate is provided to a demodulator (422) for demodulating the traffic channel symbols. The pilot symbols are provided to another channel estimator (410) for estimating channel phase and channel gain for the power control designator. This estimate is provided to a demodulator (424) for demodulating the power control designator. The traffic channel symbols are delayed a predetermined time in a delay element (420) before demodulating. The power control designator is delayed a short time or not at all in a short delay element (418) before demodulation.

Abstract: A method and apparatus is provided for synchronizing a received communication signal. A synchronization signal is derived from a received signal having a plurality of synchronization words. Each synchronization word has a predetermined number of synchronization symbols. The synchronization signal is filtered. The filtering is characterized by spacing each filter tap to correspond to synchronization word length increments. Synchronization information is generated which is based on a comparison of the filtered synchronization signal to a threshold. Finally, the synchronization information is output based on a confidence derision derived from the synchronization information.

Abstract: A frequency control apparatus and method is disclosed in which a frequency offset between a received signal and the local oscillator of a digital receiver is corrected in substantially one step.
