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 wideband front-end device comprises a wideband amplifying module and a plurality of narrow band filters. The wideband amplifying module comprises an input end, a plurality connecting ends and at least one receiving end. A wideband transmitting RF signal can be transmitted to one of the connecting ends from the input end according to the frequency band thereof. Thus, the wideband transmitting RF signal can be divided into several narrow band signals with different frequency bands. Each narrow band signal with different frequency bands is transmitted to different connecting ends and narrow band filters respectively. Therefore, each narrow band filter can be used to filter wideband transmitting RF signal or narrow band signals with different frequency bands respectively to reduce production costs of the wideband front-end device.
