We propose a novel proportional fair space time scheduling algorithm to enhance the reverse link capacity of a generic wireless access architecture. The access point is assumed to have nR antenna while the client device has single transmit antenna. We also assume slow fading channel where clients are moving with pedestrian speed. System capacity is enhanced by exploiting the burstiness of data source, selection diversity of different client users as well as the distributed MIMO configuration when we have nR antenna at the access point. We shall illustrate that the proposed algorithms could be applied to IEEE 802.11a wireless LAN system with slight modification of the MAC layer of client device. Significant gain in system capacity is found which is attributed to the distributed MIMO configuration between the access point and multiple client users as well as the selection diversity of different client users.
