Research of channel quantization and feedback strategies based on multiuser diversity MIMO-OFDM systems

Firstly, a quantization method was proposed by quantized value indicating the modulation level instead of the full values of channel quality information（CQI） and the achievable average spectrum efficiency showed no loss compared with perfect case.Secondly, employment of the integrated design that co...
