Abstract

Favorable outcome of the OFDM has been achieved that multi-carrier modulation is an well-organized offer for wireless communications. Wavelet based modulation is a recent type of modulation for transmission of signals which is multicarrier in nature on the channel which is wireless that uses the property of wavelet called orthogonality but other than the sine functions. . The modulation of the discrete wavelet transform varies with respect to some aspect to traditional method to provide better performance outcome. In this paper brief study is given on the wavelets and the BER performance comparison between the two systems of FFT based OFDM and the DWT based OFDM the analysis done for the Haar wavelet family with the modulations of PSK and QAM and simulated in the AGWN channel based on the survey of the OFDM in communication system.
