COFDM多媒体传播系统研究

摘要

With analyzing the basic principle of OFDM and studying the structure of COFDM based,introdu-cing the model of LDPC-COFDM communication system,to construct the working mechanism of real-time mul-timedia communication system COFDM,through comparing the measured parameters of the simple system work,clear COFDM technology brings strong real-time,high reliability of the high-speed mobile media work, actual work ability.%以分析OFDM的基本原理、COFDM的结构为基础，引入LDPC－COFDM通信模型系统，构建出COFDM实时多媒体传播系统的工作机制，通过比较简易系统工作的实测参数，明晰了COFDM技术带来的实时性强、可靠性高的高速移动传媒的实际工作能力。
