中文摘要：
空时分组码译码采用直接法构造判决统计量。两副发射天线、一副接收天线的空时分组码系统的判决统计量还有另外一种构造方法——匹配滤波法。将匹配滤波法进一步推广到多维空时分组码系统，给出了匹配滤波器的构造方法，并在SPW平台上对这种方法进行了仿真。分析和仿真结果表明：提出的增强匹配滤波法易于实现，适用于多维空时分组码系统，其误码性能与直接法相同。
英文摘要：
During the decoding of space-time block codes, decision statistics are constructed according to the direct method. There is another method called the method of matched filter to construct the decision statistics of space-time block codes system with two transmit antennas and one receive antenna. The method of matched filter was extended into the multi-dimensional space-time block codes system. Construction method for matched filter was proposed and simulated on the SPW platform. Analysis and simulation results show that the proposed intensified method of matched filter is easy to be carded out, it is applicable to the multi-dimensional space-time block codes system and its code error rate is the same as that of direct method.
