摘要
在正交空时分组码(OSTBC)基础上,分析了Turbo乘积码(TPC)和OSTBC级联方案的可行性,提出了一种采用TPC+ OSTBC级联的空时编译码方案,分别仿真分析了不同TPC分量码、不同接收天线数目下系统的差错性能,并对采用OSTBC和TPC+ OSTBC级联方法系统的差错性能进行了对比分析。仿真结果表明:该级联空时编码方法可同时获得全分集和全速率,且差错性能明显优于只采用OSTBC。
The feasibility of cascading TPC（Turbo Product Code） with orthogonal space-time block code（OSTBC） is analysed and a space-time coding scheme adopting TPC and OSTBC is proposed.The BER performance of this scheme is simulated under different TPC sub-codes and number of receiving antennas and compared with systems only adopting OSTBC.The simulation results show that this space-time coding scheme can achieve both full diversity and full rate and the BER performance of the cascading scheme is much better than that of scheme only using OSTBC.
