摘　　要：对码分多址技术中的一种地址码——Ｗａｌｓｈ码、短截码，及改进的Ｗａｌｓｈ码的各种相关特性进行了计算与统计，并得出结论：改进后，Ｗａｌｓｈ码的自相关特性得到显著改善。The concept of partial Walsh code and improved Walsh code that are employed in CDMA system have been proposed.Correlation properties of Walsh code, partial Walsh code and imporved Walsh code are calculated and the results are discussed.The conclusion is the auto correlation properties of improved Walsh code have been amended saliently, while the cross correlation properties of that descended.
