In order to provide the instruction in theory to design the practical multiuser MIMO-OFDM system, the performance gain concerning multiuser diversity with the perfect feedback is studied. A quantization feedback scheme is proposed by quantized values indicating the modulation level instead of the full values of the SNRs when a finite set of M-ary quadrature(More)
By applying the effective bandwidth theory of wireline network on wireless domain, a cross-layer resource allocation algorithm based on MIMO-OFDM time-frequency frame structure is introduced. This algorithm not only concerns the channel state information in the physical layer, but also pays attention to priority, fairness and delay quality of service (QoS)(More)
