SUPPRESSION OF NARROWBAND INTERFERENCE IN DS-SS SYSTEM BASED ON BLOCK FREQUENCY ALGORITHM

针对直接序列扩频系统中窄带干扰问题,采用频域批处理LMS算法进行干扰抑制.文中推导了算法的数学过程,并进行了计算机仿真,仿真结果表明,采用该算法可以较大幅度提高系统的抗干扰性能.

The technology of narrowband interference suppression is discussed. Block frequency LMS algorithm is adopted in the paper and developed. The simulation results demonstrate that the algorithm can improve the anti - interference performance.
