N2 - By replacing a circle with ellipses in constellations of MPSK (M=2,4,8), this paper propose several modulation schemes defined as M-ary Elliptical Phase Shift Keying (M-EPSK, M=2,4,8). Both mathematical analysis and computer simulations show that M-EPSK can improve power efficiency over MPSK, and have high flexibility to make trade-offs on power efficiency and bandwidth efficiency by varying eccentricities.
