Claim of US Patent No. 10,484,029

1. A receiver of signals likely to be disturbed by an interfering signal, the receiver comprising an interference rejection filter comprising a multiplying gain applied respectively to an in-phase channel and to an in-quadrature channel of a signal received and digitized by the receiver, the value of the multiplying gain being determined by a nonlinear function Ki(?) of the modulus ? of the received signal, the function Ki(?) being determined so as to maximize the signal-to-noise ratio after application of the multiplying gain and demodulation of the received signal.
