摘要
OFDM技术以他在多径和窄带干扰方面的良好性能以及高频谱利用率得到广泛应用,并成为第四代移动通信的核心技术,但是OFDM对同步非常敏感。研究了各种同步因素对系统的影响,通过仿真设计了一种基于IEEE 802.11a的OFDM宽带数据通信同步系统的设计方案,并在FPGA上实现了系统设计。
OFDM has been widely used in communication systems and is the key technology of 4G in the field of mobile communication, because of its excellent performance in overcoming multi-path channel and narrow band interfering. However the principle weakness of OFDM is sensitivity to synchronization. So synchronization is very important to OFDM systems. By researching various of the synchronization factors,according to simulation we introduce a method of realizing the synchronization system for broad band data communication based on 802. 11a,and realize the system using FPGA.
