Abstract
Multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) is regarded as a promising technology enabling higher data rate wireless communications in frequency selective fading channels. This paper proposes the next generation wireless local area network (WLAN) physical (PHY) layer transmission technology using dual-band and MIMO-OFDM schemes† It describes a design of the higher data rate WLAN system targeting the maximum speed of 144Mbps in 20MHz bandwidth channels and 288Mbps in 40MHz. Additionally, the design suggests a new frame structure based on the 802.11a frame format for guaranteeing the compatibility with IEEE 802.11a legacy-OFDM systems and the MIMO channel estimation capability. For a cost-effective implementation and improved error performance, 2 transmit and 3 receive antennas are used in dual-band.
