A Novel Scheme for Space-Time Block Coding with Variable Transmit Diversity Gain in Time-Frequency-Shift Keying Systems

  • 摘要: 将酉空时分组编码技术应用于时频调制系统中,该文提出了一种可变发射分集增益的空时/时频调制编码新方案。将已调的时频信号分解为互正交的两子信号,同时运用不同的排列组合方案即可得到不同的分集增益。计算机仿真结果表明,新方案抗平坦衰落的性能优于Alamouti空时分组编码方案及空时/频移键控编码方案,且当新方案获得二重分集增益时,其相应编码速率优于获得四重分集增益时的编码速率,但抗衰落性能劣于获得四重分集增益时的性能,所得结论与理论分析完全一致。
