Signal receiver including interference suppression filter, especially GNSS signal receiver and its method

摘要

The receiver (200) includes an interference suppression filter, which includes a phase channel (() I) applied to the signal received by the receiver and a multiplication gain () 250 applied to the orthogonal channel, where the multiplication gain value is It is determined by the ki (P) nonlinear function of the P module of the received signal. After the multiplication gain and demodulation of the received signal are applied, the ki (P) function is determined to maximize the noise signal ratio.
