摘要

OFDM由于具有较高的数据传输速率、抗衰落能力和带宽利用率，成为现代无线通信系统的关键技术。此外，为了实现无错误传输，在之前的工作中使用了各种信道码，例如卷积码(CC)，里德所罗门码(RS)和BCH码。在这项工作中，展示了一种基于OFDM的M-PSK无线系统，该系统在瑞利衰落信道上结合了多种信道编码技术。通过误码率评估作为信噪比的函数来研究模拟试验台的性能。我们的仿真结果表明，与CC和RS相比，使用BCH的仿真系统的误码率有显著改善。

BER Assessment of FEC Incorporated OFDM-MPSK Wireless System

Due to elevated data rate transmission, fading immunity and bandwidth efficient capability, OFDM comes out as a key technology in contemporary wireless communication systems. Additionally, to access error free transmission, diverse channel codes for instance Convolution Codes (CC), Reed Solomon (RS) and BCH codes are being used in the previous work. In this work, an OFDM based M-PSK wireless system is demonstrated incorporating diverse channel encoding techniques over Rayleigh fading channel. The performance of the simulated test-bed is investigated via BER assessment as a function of SNR. Our simulation results reports a significant improvement in BER of the simulated system using BCH over CC and RS.
