摘要

用户的异步性和多径传播是直接序列码分多址(DS CDMA)系统设计中最需要解决的问题之一。本文描述和研究了一种采用每个用户交叉多重签名的系统，以减轻这些因素的破坏性影响。结果表明，交错以及适当选择用户的签名群可以显著降低多址干扰中与数据调制相关的峰值水平

Signature-interleaved DS CDMA: controlling odd correlation peaks

Users' asynchronism and multipath propagation are among the most problematic issues in designing direct sequence code division multiple access (DS CDMA) systems. In this paper a system employing interleaved multiple signatures per user to mitigate the damaging effects of these factors is described and studied. It is demonstrated that interleaving along with an appropriate selection of users' signature multitudes drastically lowers the level of data-modulation-related peaks of multiple access interference
