Abstract
In multiple antenna systems, vertical Bell Labs Layered Space-Time (V-BLAST) systems enable very high throughput by nulling and cancelling at each layer detection. In this paper, we propose a V-BLAST system which combines with signal space diversity technique. The benefit of the signal space diversity is that we can obtain an additional gain without extra bandwidth and power expansion by applying inphase/quadrature interleaving and the constellation rotation. Through simulation results, it is shown that the performance of the proposed system is less than 0.5 dB away from the ideal upper bound
在多天线系统中,垂直贝尔实验室分层时空(V-BLAST)系统通过在每一层检测中进行零和抵消,实现了非常高的吞吐量。本文提出了一种结合信号空间分集技术的V-BLAST系统。信号空间分集的优点是通过相位/正交交织和星座旋转,在不增加带宽和功率的情况下获得额外的增益。仿真结果表明,所提系统的性能与理想上界差不超过0.5 dB
