摘要

本文讨论了m序列、3项序列、5项序列和Welch-Gong序列作为下行链路MC-CDMA的扩频码的峰均功率比(PAPR)特性。结果表明，对于单用户或多用户，由这些序列生成的正交码比Walsh-Hadamard序列提供更低的峰均值包络功率比(PMEPR)。因此，这些序列可以被认为是通过降低MC-CDMA系统的papr来替代Walsh码的良好选择。

Peak power control of MC-CDMA with special classes of binary sequences

In this paper, the peak-to-average power ratio (PAPR) properties of m-sequences, 3-term, 5-term and Welch-Gong sequences are discussed as the spreading codes for downlink MC-CDMA. It is shown that for single or multiple users, the orthogonal codes generated by these sequences provide lower peak-to-mean-envelope-power ratios (PMEPR) than Walsh-Hadamard sequences. Therefore, these sequences can be considered as good alternatives to replace Walsh codes by reducing PAPRs of MC-CDMA systems.
