Efficient and Fair Resource Sharing Algorithm for Multi-user MIMO-OFDM Systems
نویسنده
چکیده
In this paper, an efficient and fair algorithm for resource management in MIMO-OFDM systems is proposed. The system used for this analysis is the downlink of multi-user MIMO-OFDM system. Based on channel state information (CSI), the base station (BS) employs singular value decomposition (SVD) to transmit the MIMO channel into parallel subchannels for each subcarrier, and then subcarriers, are allocated according to a variance based algorithm. The proposed scheme is used to enhance the system capacity while satisfying the proportional fairness constraint. A selection of numerical results is presented to illustrate the performance of the proposed algorithm.
