| 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。

| Abstract: | 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. |
