摘　　要：讨论了扩频序列的选择问题,分析了一种新的扩频码序列,即改进的m序列与Walsh序列的复合序列,介绍了该序列的实现方法.通过计算机大量统计分析结果可知,该序列是一种相关性能优良的扩频码.　This paper discusses the choice of spread spectrum sequences, and analyses a new spread spectrum sequence-a composite sequence made up of Walsh sequence and advanced m-sequence. The way of realizing the sequence is presented. A conclusion is made that it is an ideal spread spectrum sequence which has acute self-correlation characteristic by means of statistical analysis with computer.
