This paper investigates the point-to-point PHY layer performance of two newly proposed IEEE 802.11n candidate solutions by suggesting extensions to 802.11a. The new solutions incorporate a MIMO architecture for the wireless links between the network terminals. The FEC block in the PHY layer chain is also enhanced with a Turbo encoder to provide interleaving gains for the larger sized PSDUs (1-4095 bytes). Due to the ambitious data rate targets identified in 802.11n, where 'on-air' data rates of up to 320Mbit/s are quoted, a large MIMO architecture comprising 6 Transmit and 6 Receive antenna elements is adopted. The paper proposes Zero-Forcing and MMSE-GIS solutions to ease complexity at the receiver.
