Abstract :
OFDM is a method of encoding digital data on multiple carrier frequency and it is one of the most popular scheme that is been widely used in most of the wireless and wired communication links. The fast growing communication for multimedia requires high speed and optimized area and power. Thus DMWT is designed to meets the above requirement. So this project proposes DMWT based orthogonal modulator. Even though DWT have the good properties but it is not satisfy the future needs. By implementing DMWT it is able to achieve good spectral efficiency and achieves good BER compare to FFT and DWT.
