摘要
介绍4G移动通信系统的关键技术OFDM(正交频分多路复用)和软件无线电的基本概念,给出了OFDM系统模型,参照802.11 a物理层的规范给出了OFDM符号帧结构,基于软件无线电的思想构建了OFDM传输系统,并用Sys-temView对OFDM传输系统的性能进行了仿真。
The basic theory of the OFDM technology and SDR, which are the key technology of the next generation network-4G are introduced in this paper. Moreover, the OFDM system model is presented. According to the proposed model and the OFDM symbol structure established by IEEE 802.11 a-1999 std., the OFDM system based on SDR is presented. In addition, a performance simulation of the OFDM system is implemented using SystemView.
