| 摘 要： | 短波通信是远距离信息传输的重要手段,OFDM(正交多载波调制)是一种在无线环境下具有较高频谱利用率的多载波调制技术。将OFDM技术应用于短波通信中,搭建了OFDM的试验平台,建立了短波通信链路,对接收端采集的基带OFDM信号进行了处理。通过编码和信道估计分别对信号进行纠错和信道补偿,处理结果表明,在传输速率600 b/s下系统的误比特率达到10-5数量级,系统性能良好。

| Abstract: | Shortwave communication has been one of the most important method of long distance commu-nication,and the OFDM(Orthogonal Frequency Division Multiplexing) is a multi-carrier modulation technique which can make good use of frequency spectrum in wireless environment.OFDM to shortwave communication is applied and the shortwave communication path between Xinxiang and Qingdao on the basis of AD9957 board is established.Through processing the baseband OFDM signal at reception,the result indicates that the system ... |
