摘要

在STBC-OFDM系统中,空时分组码提供了无线衰落信道中的发射分集。在宽带无线接入系统中,OFDM是一种克服无线信道缺陷和增强信道宽度潜能的方法。本研究分析了非STBC-OFDM系统和STBC-OFDM系统的性能。对正交频分复用(OFDM)系统中采用多发射分集天线系统的构造调制(QAM)技术的性能进行了评价。考虑罗利衰落信道中码间干扰(ISI)、相位噪声和时序噪声的影响,推导了STBC-OFDM系统中16-QAM多收发天线的信噪比和误码率方程。

Degrading the Effect of Channel Impairment on STBC-OFDM System in Rayleigh Fading Channel
This paper indicates the space time block code provides transmit diversity in wireless fading channel during the STBC-OFDM system. OFDM is enforced in broadband wireless access systems as the way to beat wireless channel impairments and to enhance and breadth potency. This research is to analyze the performance of non STBC-OFDM system and STBC-OFDM system. The performance has been evaluated for construction modulation (QAM) technique for orthogonal frequency division multiplexing (OFDM) systems using multiple transmit diversity antenna system in the channel. Conjointly the equation of SNR and BER has been derived for 16-QAM for multiple transmit and receive antenna for STBC-OFDM system by considering the have an effect on of Inter-symbol interference (ISI), phase noise and temporal arrangement noise in Raleigh fading channel.
