摘要

通过降低调制星座的维数，可以降低分组编码M-QAM的译码复杂度。本文的目的是提出一种编码方法，在M为奇次2的M- qam星座中，从渐近编码增益和带宽效率方面提高BCM的性能。

On bandwidth efficiency of BCM applied to non-square M-QAM

The decoding complexity of block coded M-QAM can be reduced by reducing the dimensionality of the modulation constellation. The aim of this paper is to present a coding method that improves the performance in terms of asymptotic coding gain and bandwidth efficiency of BCM applied to M-QAM constellations, where M is an odd power 2.
