空时编码方案的重点是将天线分集与适当的信道编码相融合，以充分利用时空分集的优势。提出了并行串联空时turbo编码调制的递归空时格码的概念。与Tarokh等人相比，新提出的方案旨在保持最大的发射分集增益，同时提高编码增益。正,Th。第44卷，没有。2, 1998)时空网格码。击穿组件代码的输出，可以在带宽效率没有成本的情况下获得相当大的功率效率改进。据报道，在130位的极短输入信息帧下，已经取得了良好的性能。
Space-time coding schemes are focused on merging antenna diversity with appropriate channel coding in order to exploit benefits of spatial and temporal diversity. We propose the concept of recursive space-time trellis codes for parallel-concatenated space-time turbo coded modulation. The newly proposed scheme was designed to preserve the maximum transmit diversity gain but simultaneously enhance the coding gain as compared to Tarokh et al. (see IEEE Trans. Inf. Th., vol.44, no.2, 1998) space-time trellis codes. Puncturing the outputs of component codes enabled a considerable improvement in power efficiency to be obtained with no cost in bandwidth efficiency. A good performance was reported already with extremely short input information frames of 130 bits.
