    Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.

    Abstract: The present invention discloses a GSM/CDMA dual-mode mobile phone and method of the same for inhibiting a GC mutual interference, wherein the mobile phone comprises a dual-port antenna connected respectively with a duplexer and a GSM RF circuit and configured to access the signals of the GSM and the CDMA; a RF switch provided in the CDMA RF receiving circuit, wherein the RF switch is controlled by a GSM baseband chip and configured to cut off a CDMA signal (i.e., cutting off a receiving path of the CDMA) transmitted/received by the dual-port antenna when a GSM operational frequency and a CDMA operational frequency belong to close frequency band during a transmitting timeslot of the GSM, to enhance the isolation between a GSM signal and a CDMA signal. The present invention inhibits interference of GSM transmission with the CDMA receiving in the circuit, achieves high isolation, and also simplifies design of the antennas, lowers requirements of the double antennas on the appearance and volume of the overall machine, and improves the flexibility in the design of the dual-mode mobile phone.

    Abstract: A configurable all-digital coherent demodulator system for spread spectrum digital communications is disclosed herein. The demodulator system includes an extended and long-code demodulator (ELCD) coupled to a traffic channel demodulator (TCD) and a parameter estimator (PE). The demodulator also includes a pilot assisted correction device (PACD) that is coupled to the PE and the TCD. The ELCD provides a code-demodulated signal to the TCD and the PE. In turn, the TCD provides a demodulated output data signal to the PE. The PACD corrects the phase error of the demodulated output data based on an error estimate that is fed forward from the PE. Accumulation operations in the ELCD, TCD, and PE are all programmable. Similarly, a phase delay in the PACD is also programmable to provide synchronization with the error estimate from the PE.
