VLSI Design of High-Throughput SISO-OFDM and MIMO-OFDM Baseband Transceivers for Wireless LAN Networks

This paper describes a VLSI design of highthroughput OFDM transceivers targeted to future wireless LAN systems. The optimum parameters composing a new packet OFDM frame are discussed by expanding the IEEE802.11a standard. The proposed system provides a maximum transfer rate of 600 Mbps by use of an 80-MHz occupied bandwidth and a MIMO technique. The SISO-OFDM and MIMO-OFDM transceivers have bee...
