摘要: 針對Volterra非線性信號處理技術(shù)所要求的計算量大的特點，該文提出了一種改進的非線性Volterra濾波技術(shù)，用于擴頻通信中干擾抑制。與常規(guī)Volterra濾波算法相比，改進算法能大大減小Volterra濾波器的長度，從而使計算量大幅下降。仿真結(jié)果驗證了該算法的優(yōu)越性。Abstract: An improved nonlinear technology of narrow-band interference suppression in DSSS communications is proposed. Compared with other Volterra filters, the algorithm proposed here can largely reduce the computational weight in a very simple way. Based on this algorithm, a DSSS receiver based on Volterra filters is investigated and simulation result proves its advantages.
