摘　　要：通信对数据业务的需求越来越高,现代战争又越来越依赖高效、可靠的通信保障,实现恶劣环境下的高速率可靠通信是重点应用研究的方向。文中对比分析了目前几种流行的调制技术,分析了这些调制编码技术的特点,并结合通信应用,分析了OFDM调制与LDPC编码的应用价值。Warfare ever relies on the highly efficient and reliable communication. So, the highly efficient and reliable communication in adverse environment has become the focus for military research. The article presents first the advanced modulation and encoding technology at present, including Tubro and LDPC in channel encoding, OFDM and SC/FDE in signal modulating. Then it analyzes the characteristic of these technologies, and in combination with the application in military communication, gives the application prospect of the OFDM and LDPC in future military communication. It may provide some reference for future development of the military communication.
