本OFDM是基于matlab 2011a simulink 制作的，如果打不开请使用matlab 2011a； OFDM采用两种映射方式一直是BPSK一种是16QAM映射，内含有实验报告两份，一份是PDF格式一份是WORD！现在实验完毕遂分享给大家！希望对大家有所帮助，也希望不要盲目抄袭，本人对实验拥有版权，严禁将本人资料随便上传！

讲述对正交频分复用理论的理解，通过分析，能够帮助读者加深理解

基于Xilinx FPGA的OFDM通信系统基带设计 光盘 代码

Orthogonal frequency-division multiplexing (OFDM) has become the favorite modulation technology for wireless communication systems. To address the needs of OFDM receiver design, we have developed this book based on course materials for a class in digital communication IC design. This book is ideal for advanced undergraduate and post-graduate students from either VLSI design or signal processing backgrounds. For engineers working on algorithms or hardware of wireless communications systems, this book provides a comprehensive understanding of the state-of-the-art OFDM design technology and will be a valuable reference.

该OFDM图书详细描述了OFDM的基本原理以及实际应用中需要解决的问题。
