摘要: The paper proposes an adaptive method for suppressing wideband interferences in spread-spectrum (SS) communications. proposed is based on the time-frequency representation of received signal from which parameters time-varying interference excision filter are estimated. approach generalized Wigner-Hough transform as effective way to estimate instantaneous frequency parametric signals embedded noise. performance evaluated presence linear and sinusoidal FM plus white Gaussian noise terms SNR improvement factor bit error rate (BER).
