摘要

为了支持可变数据速率的多码码分多址(MC-CDMA)系统被提出用于移动通信。它们允许通过改变分配给每个用户的扩展序列集来支持可变源数据速率。考虑了序列设计对系统性能的影响。对其抗衰落性能和多用户干扰性能进行了分析。我们描述的序列集在这些参数方面几乎是最优的，并且允许每个用户在不影响其他用户的情况下改变其数据速率。

Adaptive multi-rate multi-code CDMA systems

To support variable data-rates multi-code code-division multiple-access (MC-CDMA) systems have been proposed for mobile communications. They allow the support of variable source data-rates by variation of the set of spreading-sequences assigned to each user. The impact of the sequence-design on the system performance is considered. For the antifading capability and the multiuser interference performance measures are derived. We describe sequence-sets which are almost optimum with respect to these parameters and which allow each user to change its data-rate without affecting the other users.
