Abstract

This paper studies the error rate performance of multi carrier direct sequence code division multiple access (MC DS-CDMA) system in conjunction with maximum ratio combining (MRC) over Nakagami-m multipath fading channel. Multiple receive antenna structure is employed at the receiver side to provide spatial diversity in addition to the frequency diversity offered by the MC system. A closed form one-fold integration, which could be solved numerically without the need for simulations, is derived for BER performance of the system. Furthermore, numerical analysis is conducted for different MC systems over different Nakagami-m channels. In addition, tradeoff analysis is provided among different types of diversities: space, frequency and path diversities.
Nakagami-m衰落信道中多接收天线MC DS-CDMA系统的误码率性能
本文研究了在Nakagami-m多径衰落信道上结合最大比合并(MRC)的多载波直接序列码分多址(mcds - cdma)系统的误码率性能。在接收端采用多接收天线结构,除了MC系统提供的频率分集外,还提供空间分集。对系统的误码率性能,导出了一种不需要模拟就可以进行数值求解的封闭形式的一次积分。在此基础上,对不同的MC系统在不同的Nakagami-m信道上进行了数值分析。此外,还提供了不同类型的分集:空间、频率和路径分集之间的权衡分析。
