摘要: 设计空时分组码(STBC)只是获得了满分集增益,但未考虑编码增益,因此空时分组码必须和能够提供大量编码增益的外码级联.Turbo乘积码(TPC)是一种高效的编码方式,与Turbo码相比译码延时低,不具有错误平层.本文采用极具纠错性能的Turbo乘积码与空时分组码级联,构成编码的多天线OFDM系统以提高无线通信系统的可靠性,并最后对系统进行了性能仿真.

Abstract: Space-Time Block Codes(STBCs)are designed to obtain the full diversity gain. However, STBCs are not designed to achieve an additional coding gain. Therefore, STBCs need to be concatenated with an outer code which provides a significant coding gain. Turbo
