In this paper, we investigate a new solution for combined amplitude and phase modulation by employing elliptical signals. Signal characteristics of the proposed schemes are analyzed and then detection methods are investigated. The derived closed-form BER approximations, i.e. theoretical analysis results, are shown to be in agreement with simulation results. Furthermore, both results show that proposed schemes, compared conventional modulation schemes, can achieve better noise performance while suffering lower spectral efficiency, and can better realize trade-offs between error probability and spectral efficiency by dynamically varying eccentricity.
