摘　　要：针对检测低信噪比直扩信号的困难,介绍了一种将经过处理后的功率谱累积以提高对低信噪比直扩信号检测能力的方法,该方法实现方便,通过计算机仿真表明比单纯增大运算数据量的方法效果好,且更具灵活性。In order to solve a difficult problem on detecting of low signal - to- noise DS/SS signal, a method which is based on a cumulation of proceeded power spectrum is presented . Applying this method is very easy. The results of computer simulation show that effects of this method is better than that of increasing the amounts of data simply and this method is more convenient.

关 键 词：直接序列扩频信号 功率谱 累积
