显示了存在的相关关系的4PSK码的性能接收天线。检查出使用性能更高的跟踪从5.4.5节中给出的代码表。空时格码的代码如何从比较的角度来看STBC的编码鲁棒性的相关性存在(shows the performance of 4PSK codes in the presence of correlation between receive antennas. Check out the performance using higher trace codes from the tables given in Section. How do STTC codes compare with STBC codes from the point of view of robustness in the presence of correlation?)
