In this paper, the authors reduce the PAPR of transmitted OFDM (Orthogonal Frequency Division Multiplexing) signals, improve the transmitted image quality & the SPIHT coder is chosen as the source coding technique due to its flexibility of code rate and simplicity of designing optimal system. Trigonometric transforms are used in this scheme for improving the performance of the OFDM system and reducing the Peak-to-Average Power Ratio (PAPR) of OFDM signal. OFDM is an efficient method of data transmission for high speed communication systems. The PAPR is a major drawback of multicarrier transmission system such as OFDM.
