Résumé: The aim of this letter is to analyze a modulation technique called {m-QAM}<superscript>2 in terms of bit error rate (BER). The performance of the {m-QAM}<superscript>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<superscript>i and i = <Root>m,<Etc.>, 2<Root>m - 1. Performance curves obtained by the theoretical model and by computer simulation are shown.
