| 摘 要： | 基于多载波并行传输的码分多址技术(MC-CDMA)是第三代数字移动通信系统研究中的一个热门课题。将信道纠错编码(卷积码和Turbo)技术与MC-CDMA系统相结合，充分利用了纠错编码(特别是Turbo)在低信噪比时的优异性能，大大提高了系统的纠错能力。分析了系统在不同信道中的误码性能，并给出相应的计算机模拟结果。

| Abstract: | The multi-carrier CDMA system is an important subject in the study of the third generation digital mobile communication systems. This paper combines the channel error-correcting coding (convolutional code & Turbo code) with MC-CDMA systems, thus sufficiently exploits the excellent performance of error-correcting coding (especially Turbo code) under low SNR, The BER performance of the system in different channels is analyzed, and the simulation results are given. |
