摘要
提出了一种联合奇异值分解(SVD)和非线性滤波抑制直接序列扩频通信(DS/SS)中单音干扰的方法,建立了相应的系统模型。并对传统的线性双边滤波器的信噪比增进因子和误码率进行了比较。仿真结果表明,奇异值分解的非线性滤波方法对干扰有很强的抑制能力,较好地改善了系统的性能。
A system model employing the proposed SVD - based nonlinear technique to reject the single - tone interference in a direct sequence spread spectrum (DS/SS) system is presented. Simulation results show that the nonlinear filtering method based on SVD technique has strong interference suppression ability.
