Limited Feedback Precoding for Spatial Multiplexing Systems Using Linear Receivers

  title={Limited Feedback Precoding for Spatial Multiplexing Systems Using Linear Receivers},
  author={David James Love and Robert W. Heath},
Multiple-input multiple-output (MIMO) spatial multiplexing wireless systems achieve high spectral efficiencies by demultiplexing the incoming bit stream into multiple substreams. Spatial multiplexing is of practical importance because the multiple substreams can be decoded using linear receivers. Unfortunately, this reduction in complexity degrades the probability of error performance. To overcome this difficulty, error rate performance of spatial multiplexing systems can be improved by sending… CONTINUE READING
