Accordingly, the interception and radio monitoring for spread spectrum communication have been of great research interests. And the chief task is to detect and separate the DS/ CDMA signals hidden in the noise and interference. 相应地,扩频通信的电子对抗和民用无线电资源监管成为非常重要的研究课题,其中对噪声和干扰中直扩码分多址(DS/CDMA)信号的盲检测和分离是首要任务。
