Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier technique, capable of coping with highly dispersive channels. In this paper, authors choose Trellis Coded Modulation (TCM)-OFDM, instead of Convolutional Code (CC)-OFDM adopted by HIPERLAN/2 and IEEE802.11a, to ease the SNR requirement. Also emphasized is the structure of the OFDM receiver, including synchronizers in every aspect and the data aided (DA) equalizer. This paper focuses on the design and simulation of the high-speed OFDM system suitable for Wireless Local Area Network (WLAN) applications with the consideration of software radio implementation.
