本文论述了格形编码调制(TCM)技术的基本原理及国内外发展状况.证明TCM技术可应用于超短波数据通信中,理论分析和计算机模拟证明这种新技术比常规设计方法有3—6dB的编码增益.对改善超短波数据传输可靠性提高信息的传输速率有明显的效果.
This paper discusses the basic principle of Lattice Code Modulation (TCM) technology and its development at home and abroad. It is proved that TCM technology can be applied to ultrashort wave data communication. Theoretical analysis and computer simulation prove that this new technique has 3-6dB Coding gain.To improve the reliability of ultra-shortwave data transmission and improve the transmission rate of information has a significant effect.
