Application of WLF to OFDMA MU-MIMO Systems II: Frequency-Domain Packet Scheduling

We propose a Mutual Information (MI) based spatial frequency domain packet scheduling algorithm for uplink Orthogonal Frequency Division Multiple Access (OFDMA) multiuser multiple-input, multiple-output (MIMO) systems in this paper. The proposed scheduler is designed particularly for signal constellation constrained MIMO systems. The superiority of the investigated scheduler coupled with the innovative iterative receiver scheme over conventional solutions is verified by both simulation and analytical results.
