In this paper, we analyze high-rate wireless LAN system based on Orthogonal Frequency Division Multiplexing(OFBM) transmission method. For this analysis, actual channcl measurement model of indoor office areas such as JTC model was adopted, and cllanncl coding of IEEE 502.11 and channel equalizer over multipath environment are also considered.

In this paper, we analyzed the performance of OFDM system based on IEEE 802.11a specification. First, we modeled the transmitter and receiver of OFDM (Orthogonal Frequency Division Multiplexing) system. Then, we analyzed the performance of OFDM system through simulation over the JTC (Joint Technical Committee) realistic channel model. In addition we carried out the performance by using pilot training symbol, which is one of the channel estimation methods, over the same channel environments.
