dc.description.abstract | In this paper, we consider opportunistic packet
scheduling with the use of reduced channel information in multiuser OFDM wireless systems. The amount of channel information can be reduced by exploiting the correlation characteristics in the frequency domain. For a given amount of feedback information, the subcarriers are selected to maximize the system capacity. A simplified algorithm is proposed for the selection of subcarriers, making the proposed scheme realizable. Simulation results show that the proposed scheme provides significant performance improvement over conventional schemes especially when the channel is highly correlated in the frequency domain and/or the amount of allowable feedback information is small. | en |
