摘要 随着高速无线数据通信的发展,自适应调制技术逐渐成为业界研究的热点之一。研究了MQAM自适应调制技术,分析了自适应调整区间的划分方案,设计了基于Turbo乘积码的自适应编码调制方法,提高了系统的频谱利用率。 adaptive coded modulation system based on subband wideband OFDM technology is designed. Also the four adaptive transmission schemes are proposed. In the end of this paper, capacity of the adaptive system is given.
