Initially only one mother wavelet is created and later scaled version of mother wavelet is derived for each bits in digital data. The scaled wavelets is used to perform digital modulation. The Performance of proposed technique is compared with conventional modulation schemes in terms of bit error rate (BER) and power efficiency (PE).
