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