摘要

提出了一种空时分组码(STBC

space-time block-code)多音调制CDMA(MT-CDMA)系统结构。对系统上行链路误码率(BER)性能进行了理论分析

推导出了在多径衰落信道下采用最大比合并时系统的BER表达式

并通过计算机仿真进行了验证。数值结果表明由于联合的空时与多径分集增益

使系统的BER性能、差错地板和容量都得到了显著地改善。

Abstract

A space-time block-coded multitone code-division multiple-access（STBC MT-CDMA） system was proposed.The uplink bit error rate（BER） performance of the proposed system with maximum ratio combining（MRC） was theoretically analyzed in a multipath fading channel and the corresponding BER expressions were derived

which was verified through simulations.Numerical results show that the BER performance

error floor and capacity of the proposed system are improved significantly due to the joint space-time and path gain.
