摘要
根据直接序列扩频码分多址(DSCDMA)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。
Based on the interference resulting from DSCDMA 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.
