摘要：Orthogonal Frequency Division Multiplexing (OFDM) is a technique, in which a single high rate data-stream is divided into multiple low rate data-streams which is modulated using sub-carriers, which are orthogonal to each other. In this paper, an image is compressed using DWT, and the compressed data is arranged in four sub bands. These are then packetized and serially mapped to the OFDM system. After receiving the channels at the receiver the bad channel is dropped at the receiver side. MATLAB simulation has been analysed to check the performance of our proposed scheme, for quality of image and energy saving and comparison is done for BPSK, QPSK and 16PSK Modulations
