Abstract

Abstract

In this paper, lapped orthogonal transform(LOT) is applied to orthogonal frequency division multiplexing(OFDM) system for modulation and demodulation, and a new OFDM scheme is proposed. The performance comparison between the new scheme and traditional OFDM system using DFT is given. It shows the new scheme can decrease bit error rate(BER) efficiently in wireless communication.
