| 摘 要： | 文章提出了在瑞利信道中,8PSK调制模式下多级编码空时分组编码级联的MLC-STBC方案,并在系统码率为2.032bit/s、发射天线为2、接收天线数目为1的条件下,分别对多级编码和MLC-STBC级联编码进行了仿真。仿真结果表明,基于8PSK,在瑞利衰落下利用旋转距离度量规则选择分量码码率的MLC-STBC系统,能获得比较理想的系统增益。

| Abstract: | In this paper,multilevel coding(MLC)based on the novel distance metric with 8PSK modulation in the Rayleigh fading channels is proposed,and at the same time,the characteristics of space-time coding are analyzed.According to the novel distance measure,a MLC with parallel decoding of levels(PDL)system is constructed with good performance in the first modulation.The second simulation indicates that the concatenation scheme combining MLC and STBC according to the new distances metric rules to design the multilevel coding using 8PSK mapping in Rayleigh fading channels can obtain a fairly ideal system gain. |
