in recent world, video and image compression have become very essential. There are many applications where we need to use different transform techniques to convert the signal or data in frequency domain. That’s why; availability of powerful software design tool is a fundamental requirement to take advantage of many advanced and specialized resources included in the latest devices. As we move in to the future there is a rising demand for high performance, high capacity and high bit rate wireless communication systems to integrate wide variety of communication services such as high-speed data, video and multimedia traffic. The separation of the sub carriers is theoretically minimal such that there is a very compact spectral utilization. DWT is faster than FFT hence it’s replaced by transform technique for OFDM. In this project we propose a multiplier less structure for FPGA hence cost effective. The main advantage of this improvement is that it can get the same throughput as traditional polyphase methodology. This project presents a novel approach to realize the DA algorithm. We propose to implement the architecture of DWT processor and verify the results on Spartan 3E FPGA. We will use MODELSIM for the verification of functional results of our scheme. We will try and compare the results with other proposed designs. We propose to implement DWT using Verilog HDL and it will be synthesized using Xilinx ISE.
