摘要
基于数据块传输模型,将窄带MIMO并行干扰抵消接收机推广到宽带MIMO信道,在理想信道和信道估计下,通过仿真评估了所提出的宽带MIMO并行干扰抵消接收机的性能。仿真结果表明:所建议的方案在宽带MIMO信道下的性能好于窄带MIMO信道下的性能,在宽带MIMO信道下,接收机可获得比窄带下更大的分集增益。
Parallel interference cancellation receiver in flat fading MIMO channel was directly applied to frequency selection MIMO channel based on block transmission model.The performance of proposed wideband receiver is evaluated based on perfect channels and channel estimation cases oby computer simulation.Simulation results states the performances of MIMO space time processing algorithms based on frequency selective channel have the advantage over the algorithms based on flat MIMO channels,and the receiver can obtain more diversity gain than it is in flat MIMO system.
