Abstract

In this paper, we propose an OFDM-based image transmission system using the information of channel magnitude response. Transmitter of the proposed system reorders OFDM input sequence according to the channel magnitude response for high quality image transmission. In reordering input sequence of OFDM, the lower spatial frequency components of an image are assigned to the OFDM subcarriers transmitted on the frequency band with the higher channel magnitude response, and vice versa. The channel is assumed to have a spectrum of two ray fading. Through the simulation, it is found that the received image quality of the proposed system outperforms that of conventional system.
