Abstract :
This paper presents the results of a study of Quadrature Amplitude Modulation (QAM) coherent reception bit by bit. The research was conducted using statistical modeling methods; the results are compared with the statistical modeling calculation of analytical expression given in previously published documents. In the last year, the discrete signals became widely employed; and with more perspective in the digital systems for transmission of information, the QAM signals became more beneficial due to its high spectral efficiency. The satellite communications systems are evolving very quickly, so the purpose of developing this kind of research is to maximize the efficiency in the communication rate with the minimal error, during the limited communications time while satellite transits the user´s horizon.
