Abstract: This novel mobile CDMA station incorporates the global positioning system (GPS). Two modes of operation are possible. One, during GPS operation, there is no transmission or reception of CDMA services. Two, simultaneous CDMA transmissions and reception of GPS are provided. When the mobile receiver is in the CDMA mode, a signal path selector selects the CDMA RF section and the GPS RF section is powered down. During GPS operation, the GPS RF section is selected and the CDMA section is powered down. When CDMA operation is compared with GPS, the average current draw can be less, as the system swaps between the RF sections. The GPS RF section may accept an antenna input from a multi-band antenna network or a separate GPS antenna. The GPS signal is propagated through the existing CDMA channel select filter, having a 1.23 MHz bandwidth and is processed in a base-band signal processor.
