摘要

本文介绍了BPSK、QPSK、16QAM、64QAM /多用户正交频分多址(MU-OFDMA)和正交频分多址(OFDM)系统在使用不同长度的循环前缀时，误码率(BER)与信噪比(SNR)的关系。分别在AWGN和Rayleigh衰落信道上进行了仿真，并对两种信道的仿真结果进行了比较。在这些结果的基础上，论文的最后一章强调了一些结论。

Multi User Orthogonal Frequency division Multiple Access (MU-OFDMA) performances in AWGN and fading channels

This paper presents the performances of BPSK, QPSK, 16QAM, 64QAM /Multi User Orthogonal Frequency division Multiple Access (MU-OFDMA) and Orthogonal frequency-division multiplexing (OFDM) systems performances in terms of Bit Error Rate (BER) as a function of Signal to Noise Ratio (SNR) using different lengths of Cycling Prefix. The simulations were carried out over AWGN and Rayleigh fading channels, and the results for the two systems have been compared. Based on those results, a number of conclusions have been highlighted in the last chapter of the paper.
