| 摘 要： | 基于最大容量和最小差错率准则,研究了在GMD V-BLAST系统中的天线选择问题.选用以信道矩阵非零奇异值的几何均值最大化为目标函数,可以避免容量与差错率性能之间的矛盾.在所有可用天线中进行选择的全搜索算法虽有最佳性能,但复杂度太高.基于贪婪算法,对发射天线采用快速的逐增选择策略.对接收天线采用快速的逐减选择策略,可以显著降低计算的复杂性.计算机仿真结果表明,所采用的快速天线选择算法可以较低的复杂度获得接近全搜索法的容量和分集增益.

| Abstract: | The antenna selection technology for Geometric mean decomposition(GMD) Vertical Bell lab layered space-time(V-BLAST) systems is studied based on maximizing capacity criterion and minimizing error probability criterion in this paper.Maximizing the geometric mean of the nonzero singular values of the channel matrix as a target function for antenna selection can avoid the contradiction between the capacity and SER performance,by which we adopt it throughout the discussion of selection algorithm.The exhaustive ... |
