摘要: An efficient feedback design for single carrier frequency division multiple access (SC-FDMA) input output (MIMO) communication systems is described. We consider a codebook-based approach MIMO pre-coding and quantization of information. Differential processing used to generate the updates iteratively information between instances. combined differential non-differential considered reduced overhead improved performance. A with periodic error reset The performance using pre-coding/transmit beamforming described evaluated SC-FDMA systems. effects quantization, sub-carrier grouped delay are investigated.
