| 摘 要： | OFDM是一种多载波调制技术,具有良好的抗频率选择性和频带利用率。IEEE802.16a协议物理层支持的空中接口规范之一就是基于OFDM调制技术的WirelessMAN-OFDM系统。OFDM系统与多天线系统结合可以在系统性能方面都有显著的提高,被视为下一代移动通信的关键技术。本文以两发两收(2Tx-2Rx)系统为例,研究基于IEEE802.16a的MIMO-OFDM宽带无线系统,并对系统的性能进行了仿真。

| Abstract: | OFDM is a multicarrier modulation technology, which has a robustness to the frequency selective fading as well as good bandwidth efficiency. One of the two air interface specifications supported by physical layer of IEEE standard 802.16a is Wireless MAN-OFDM system based on OFDM modulation technology. The combined application of multi - antenna technology and OFDM modulation will increase the system performance dramatically. In this paper, we describe and simulate a multiple-input multiple-output OFDM broadband wireless based on a 2Tx - 2Rx system in detail. |
