基于FPGA 的OFDM 宽带数据通信同步系统设计与实现:正交频分复用（OFDM）是第四代移动通信的核心技术，本文介绍了一种基于FPGA的OFDM 宽带数据通信同步系统的设计方案，该方案为OFDM 多载波通信提供了必要的同步系统。通过仿真完成了系统方案的设计，并利用Altera 公司的CycloneII 器件实现了整个同步系统设计。通过测试，论证了方案的可行性。关键词：正交频分复用 同步 码间干扰 多载波调制 载波间干扰Abstract: OFDM is the key technology of 4G in the field of mobile communication. This paperintroduce a method of realizing the synchronization system for broad band data communication based on FPGA, this method provides the indispensable synchronization system for OFDM multi-carriers communication. According to simulation we finish the design of scheme, and then using the CycloneII FPGA of Altera Company realize the whole design of synchronization system. Through testing, demonstrate the feasibility of this scheme.Key Words: OFDM Synchronization ISI MCM ICI
