摘要
介绍V-BLAST系统的基本结构和信号检测算法,分析各种算法的优劣,并给出采用MMSE信号检测算法的仿真性能。由于信道矢量之间的相关性对系统的分集增益有影响,仿真不同相关值对系统性能的影响。仿真结果表明,天线相关值越大,系统分集增益越差。
Introduces the basic structure and signal detection algorithm of the V-BLAST system, compares the performances of various algorithms, gives the influence of different correlation value on the system pedormance under the MMSE signal detection algorithm. The simulation results show that the greater antenna correlation value eorrespond the worse performance of the system.
