现代战争越来越依赖高效、可靠的通信保障,实现恶劣环境下的高速率可靠通信是我军需要重点研究的方向。文中首先介绍了目前国内外比较先进的调制编码技术,包括信道编码技术中的Tubro、LDPC码,信号调制中的OFDM与SC/FDE技术,然后分析了这些调制编码技术的技术特点,结合军用通信的应用背景,给出了OFDM调制与LDPC编码在军用通信中的应用前景。
Modern warfare relies more and more on efficient and reliable communications support. To achieve high-speed and reliable communications in harsh environments is a direction our military needs to focus on. The paper firstly introduces the most advanced modulation and coding techniques at home and abroad, including Tubro and LDPC codes in channel coding, OFDM and SC / FDE in signal modulation, and then analyzes the technical characteristics of these modulation and coding techniques. Combined with military communications The application of OFDM modulation and LDPC coding in military communications applications are given.
