摘要 分析了级联正交 /长 PN码的互相关和自相关特性。分析的结果用来计算在这种新的扩频方案下直接扩频系统在多用户和多径衰落下的系统性能。多径衰落信道为相关 Nakagami信道。接收端采用最大比率分集接收机。 In this paper,the crosscorrelation and autocorrelation properties of the concatenated Orthogonal/long PN sequence are analyzed .The results are used to evaluate the performance of the new spreading scheme for direct sequence spread spectrum CDMA in a multiuser and multipath fading channel.The channel is assumed to be correlated Nakagami.The maximum ratio combiner is used in receiving signals.
