| 摘 要： | 空时分组码和分层空时码相结合的STBC-VBLAST系统，能够利用两者的优点提高系统的性能．但在空间相关信道下，混合系统的性能也将受到一定影响，我们在不同的空间相关性下对系统的性能进行仿真及分析，得出在空间相关系数大于0．5之后，系统衰落加剧，性能较差．

| Abstract: | A new STBC-VBLAST scheme which combined STBC （Space-Time Block Coding） system and BLAST （Bell Layered Space-Time Architecture）system, can enhance the performance by using the advantage of both system. But the performance of combined system will be affected in spatially correlated channels. After simulation and performance analysis in different spatial correlation we get the conclusion that capability of system is weaker when the space-related coefficient of more than 0.5. |
