一种改进的满分集高速率空时分组码的设计

Design of a new full diversity high rate orthogonal space-time block coding

为了提高空时分组码的误码性能,本文针对一种仅适用于BPSK调制的新的空时分组码,提出了一种改进的基于双QPSK调制的空时分组码方案。于原方案相比本文提出的编码方案每次能传输的比特数高4比特,而且通过仿真分析可以证明其误码性能得到明显的改善。

In order to improve the BER performance of STBC,we proposed an improved space-time block coding（STBC） scheme base on a new scheme which using BPSK modulation.Our scheme using a special modulation scheme called twin QPSK.Compared with the old scheme it can transfer more than four bits each time.The simulation results show that the BER performance is significantly improve compare to the old scheme.
