    ABSTRACT


    In this paper we present an energy saving approach to transmission of discrete wavelet transformation based compressed image frames over the OFDM channels. Based on one-bit channel state information at the transmitter, the descriptions in order of descending priority are assigned to the currently good channels used in Huffman and SPHIT Encoding. Analytical evaluation of the system in terms of probability of error is carried out in a diffused wireless channel. As a conclusion, the proposed system shows promising results for a high speed wireless channel and we demonstrate the usefulness of our proposed scheme in terms of system energy saving without compromising the received quality in terms of peak signal to noise ratio. Despite using more number of carriers  instead  subset of carriers is usable for successful data transmission and permitting the retransmission of lost packets. The improvements that can be realized in various performance parameters in a digital Communication system using wavelets. Parameters like Spectral efficiency, Mean square error, Peak signal to noise ratio (PSNR) and bit error rate are found to improve with the help of wavelets.
