摘要 提出一种新型的复编码分集正交频分复用 (OFDM)系统 ,发送端 N (载波个数 )个复编码数据符号按如下方法构成 :同相分量与正交分量的序号相差 N /2 ,这样就可以使得相同符号出现在间隔为 N /2的载波上 .在接收端只采用简单的等增益合并就可以获得分集好处 .通过分析与仿真计算可以看出 ,复编码分集可以大大改善 A new OFDM system with complex coding diversity comprising N subcarriers is proposed. The transmitted data symbols are grouped in complex format: the in phase side and the quadrature side of the symbols are arranged with N/2 intervals. The system performance can be improved greatly by analysis and computer simulation without increasing the transmitting power.
