Abstract

A knowledge-based interference rejection scheme for removal of narrow band interference (NBI) in direct sequence spread-spectrum systems (DSSS) is presented. The interference rejection system monitors the environment and identifies the types of interference embedded in the DSSS signal. An accurate estimate of the characteristics of the NBI is obtained and is used to direct the subsequent interference rejection schemes. The system performance is illustrated by means of simulation results.

直接序列扩频系统中一种基于知识的干扰抑制方案
提出了一种基于知识的直接序列扩频系统(DSSS)窄带干扰抑制方案。干扰抑制系统监测环境并识别嵌入在DSSS信号中的干扰类型。得到了NBI特性的准确估计，并用于指导后续的干扰抑制方案。仿真结果说明了系统的性能。
