Whereas study indicates that by adding preprocessing unit before correlation despreading unit in receivers, the narrowband interference rejection ability may be improved greatly. At the same time, spread factor spread spectrum system itself has may not be added.
然而研究表明,通过在扩频接收机的相关解扩环节前加上预处理环节,则可以大大提高扩频接收机的抗窄带干扰能力,而扩频系统本身的扩展因子则无需加大。
