摘要
本文以Ｕｎｇｅｒｂｏｅｃｋ的格状编码理论为依据，研究了１６ＱＡＳＫ上的ＴＣＭ技术，结果表明，该调制方式与常规的调制方式相比，可以获得５－６ｄＢ的编码增益。
The study of the technique of 16QASK TCM modulation is based on the theory of trellis coding presented by Ungerboeck The research demonstrates that the modulation with trellis coding may obtain 5-6dB coding gain in comparison with the conventional modulation
