Abstract

In this paper, for multi-user multiple-input-multiple-output (MU-MIMO) orthogonal frequency-division multiplexing (OFDM) downlink system, we have proposed a weighted frequency-selective scheduling (WFSS) scheme. This scheme achieves a net throughput enhancement by adjacent subcarriers grouping into chunks and weighting factor which is obtained from earlier period throughput. To solve the overhead issue, optimized chunk size is used here. Comparison of net throughput between the proposed schemes and various other scheduling schemes is performed. The result shows that the weighted FSS scheme achieves improvement in the net throughput and average sum rate
