【摘要】 根据直接序列扩频码分多址（ＤＳＣＤＭＡ）系统多址干扰形成原理，着重分析了ｍ序列、Ｇｏｌｄ序列、Ｗａｌｓｈ序列及其正交性。计算机模拟结果表明，同步状态下Ｗａｌｓｈ序列有理想的正交性，但在非同步状态下正交性不很理想。更多还原

【Abstract】 Based on the interference resulting from DSCDMA system, this paper emphatically analyses m sequence, Gold sequence, Walsh sequence and their respective correlation. The computer simulation results indicate that the correlation of Walsh sequence in synchronization systems is ideal, while it’s not very good in asynchronization systems.更多还原
