    Abstract: A method and system using correlator circuitry in a GPS baseband circuit for despreading both GPS data and local wireless data. In one embodiment, an RF signal (local wireless) is received at a first frequency and a digital baseband signal is produced therefrom at a second frequency. A GPS signal is also received at the second frequency and a digital baseband signal is produced therefrom. Both baseband signals are provided to a single GPS baseband circuit for data recovery. In a GPS mode, GPS data is recovered from the baseband signal by despreading and demodulation. In a local wireless mode, the GPS baseband circuit is programmed to despread and recover local wireless data. The GPS data and the local wireless data can be stored in a data buffer for downstream processing. By sharing the correlator circuits in the GPS baseband circuit for both GPS data recovery and local wireless data recovery, a low cost receiver unit is provided. In one embodiment, the local wireless baseband signal is produced by up conversion of the local wireless RF signal and then processing though a common RF front-end circuit that is also used by the received GPS signal.

    Abstract: In a CDMA based wireless digital communications system, a CDMA communications station. A CDMA communications station includes a signal encoder adapted to encode signaling information into a signaling packet. A voice encoder is also included to encode voice information at a variable data rate and process the voice information into a voice packet. A multiplexer is coupled to receive the voice packet from the voice encoder and coupled to receive the signaling packet from the signal encoder. The multiplexer combines the voice packet and the signaling packet into a traffic frame. A transmitter is coupled to the multiplexer for transmitting the traffic frame as received from the multiplexer. The multiplexer is further coupled to receive an early data rate indication from the voice encoder such that the multiplexer is able to preconfigure the traffic frame for the variable data rate voice packet to be delivered once the processing of the voice encoder is complete. This allows the traffic frame to be sent to the transmitter for transmission immediately upon reception of the voice packet from the voice encoder, thereby reducing the latency of the digital communications system.
