Abstract

Consecutive mean excision (FFT-CME) interference suppression algorithm has little effect on broadband non-stationary interference for direct sequence spread spectrum (DSSS) system, such as chirp interference. To address this issue, a new DSSS system integrated interference suppression algorithm is proposed in this research. The algorithm is on the basis of discrete polynomial transform (DPT) and Newton iteration algorithms. Combined with FFT-CME interference suppression algorithm, it could effectively suppress three typical interferences: narrow-band single tone interference, stable wide-band interference, and the chirp interference. Simulation results show that the proposed algorithm has good suppression effect to the three typical interferences, even the ratio of interference to signal is up to 50 dB.
