摘要
从误码率和PN码捕获两个方面,分析采用时域预白化滤波器和双边插值滤波器的DS-CDMA抗窄带干扰接收机性能,结果表明,抗干扰滤波器可显著改善接收机误码率的性能,但同时使得PN码相关输出产生较大的相关旁瓣,对PN码捕获性能产生严重影响。
The performance of DS-CDMA time domain narrowband interference suppression receiver,which adopts the time domain linear pre-whiting filter and two-side linear interpolation filter,is analyzed from the Bit Error Rate （BER） and the PN code acquisition. The result proves that the interference suppression filter can materially improve the BER,but large side-lobes are formed in the output of correlator,and the performance of PN code acquisition is seriously affected.
