OFDM is multicarrier modulation (MCM) technique which provides an efficient means to

handle high speed data streams on a multipath fading environment that causes ISI. Normally

OFDM is implemented using FFT and IFFT’s. To decrease the BW waste brought by adding

cyclic prefix, wavelet based OFDM is employed.-OFDM is multicarrier modulation (MCM) technique　which provides an efficient means to
