| 摘 要： | 近几年来,无线通信技术正发生着巨大的变化,无线传播的独特功能如反射,折射等,包括多径衰落,路径损耗的结果和多普勒频移,使无线通信具有高速的信息传递功能。此外无线通信信道由于不同的结构,在互联网中由于数据包的损失而引起的网络拥塞已不再只是无线环境下的问题了。OFDM和MIMO两种技术的结合使得多用户在无线信道中传输成为可能,本文通过对比两种不同信道估计技术,改善了无线信道估计的性能。

| Abstract: | In recent years,wireless communication technologies are undergoing tremendous change,the unique features of wireless communication such as reflection,ect,including multipath fading,path loss and Doppler frequency shift of the results,making high-speed wireless transmission of information function.In addition,the wireless communication channel due to the different structure of the Internet packet loss due to network congestion caused by the wireless environment is no longer just a question.OFDM and MIMO combination of two technologies enables multi-user wireless channel transmission is possible in this paper by comparing two different channel eatimation techniques,to improve the performance of radio channel eatimates. |
