Abstract: An apparatus and method for improved processing of audio and video in the wireless multimedia communication. By setting a SNR estimator in the de-modulator and connecting a PLC trigger between the de-modulator and the PLC module in parallel. The SNR estimator can calculate the signal to noise ratio (SNR) of the wireless signal in the de-modulator directly. The PLC trigger can calculate the losing condition of the digital signal and make the decision whether proceeds the packet loss concealment (PLC) depend on the condition to make the PLC to the highest efficiency.

Abstract: The present invention provides an apparatus and method for reducing harmonic interference to GPS signal reception. The apparatus comprises a RF transceiver module, a GPS signal reception path, and a harmonic distortion predictor. The RF transceiver module generates a first signal to be transmitted. The harmonic distortion predictor is used for establishing an estimated harmonic distortion sample based on the first signal. The GPS signal reception path receives an analog GPS signal, and converts the analog GPS signal into a digital GPS signal. The digital GPS signal subtracts the estimated harmonic distortion sample to obtain an accurate digital GPS signal. Thereby, the harmonic interference may be eliminated from the GPS signal in digital domain by means of digitally form so as to reduce distortion of the GPS signal.

Abstract: A tuner for crosstalk cancellation comprises a plurality tuner units and a crosstalk cancellation unit, wherein the crosstalk cancellation unit is connected to each tuner unit. Tuner units are used for receiving analog signals with same frequency band or different frequency bands respectively, and converting the analog signal to a digital signal. The crosstalk cancellation unit receives digital signals from each tuner unit, and executes operation or algorithm of each digital signal to cancel the crosstalk of each analog signal on tuner units and/or analog front ends.
