Performance analysis of angle modulated MQAM transmission techniques
A novel method of digital modulation with a high spectral efficiency, called the Angle Modulated M-ary Quadrature Amplitude Modulation. The main advantage of EM-MQAM is an ability to transmit a multilevel MQAM constellation as a constant envelope signal.
