ESQUEMA M-ÁRIO DE MODULAÇÃO POR CHAVEAMENTO DE WAVELETS

In this work, a new M-ary modulation scheme based on wavele tshift keying (M-WSK) is introduced. The scheme is presented as a viable alternative to the usual digital modulations (FSK, PSK and QAM), when measuring a bit error rate (BER) on a channel with AWGN. By means of computational simulations, WSK performance in terms of BER was found to be systematically better than the performance of FSK and PSK modulations and was similar to the QAM for constellations of 4 to 64 symbols
