The aim of this letter is to analyze a modulation technique called {m-QAM}(2) in terms of bit error rate (BER). The performance of the {m-QAM}(2) is compared to the traditional M-QAM modulation scheme, taking into account the same spectral efficiency, where m and M are related by M = 2(i) and i = rootm,..., 2 rootm - 1. Performance curves obtained by the theoretical model and by computer simulation are shown.51042642
