摘要

本文研究了多用户环境下具有RAKE接收机的多载波扩频码分多址(MC-SS)系统。研究了非理想MC-SS码信号的自相关和互相关特性对系统性能的影响。考虑到这些相关行为，导出了误码概率的表达式。此外，还将MC-SS CDMA系统的性能与基于Gold序列的直接序列扩频(DS-SS)系统进行了比较。

Investigations of bit error floors for multi-carrier spread-spectrum CDMA systems with RAKE receiver in frequency-selective channels

In this paper, a multi-carrier spread-spectrum (MC-SS) code division multiple access (CDMA) system with RAKE receiver is investigated in a multi-user environment. The impact of the non-ideal MC-SS code signal auto- and cross-correlation properties on the system performance is examined. Terms for the probability of bit errors are derived considering these correlation behaviors. Furthermore, the performance of a MC-SS CDMA system is compared with a direct-sequence spread-spectrum (DS-SS) system based on Gold sequences.
