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 method of suppressing single-tone interference in direct sequence spread spectrum communication (DS / SS) by combining singular value decomposition (SVD) and nonlinear filtering is proposed. The corresponding system model is established. The SNR enhancement factor and bit error rate of traditional linear bilateral filter are compared. Simulation results show that the singular value decomposition of the nonlinear filtering method has a strong ability to suppress interference, better to improve the performance of the system.
