Multicarrier modulation, and especially OFDM, is one of the remising candidates that uses a set of subcarriers in order to broadcast the information symbols in parallel through the communication channel. It permits the communication system to broadcast the data at a lower rate on plurality of subcarriers and the throughput of multicarrier system remains as single carrier system. This allows us to design a system that supports high data rates, while maintaining symbol span much longer than the channel delay spread, thus reduce the need for complex channel equalization mechanism.To maintain the orthogonality in multi career OFDM communication cycle prefix is used. The drawback of cyclic-prefix insertion is that only a fraction of the received signal power is actually utilized by the OFDM demodulator, implying a corresponding power loss in the demodulation. In addition to this, cyclic-prefix insertion also implies a corresponding loss of bandwidth efficiency. In this research, we have addressed the problem of energy efficient image transmission system for OFDM in which we have used discrete trigonometric transform and discrete wavelet transform based OFDM system. We have also done performance assessment for the given system based on BER and PSNR. Simultaneously the given system has been tested for Rayleigh and fading channel under parametric variation.
