This paper aimed to evaluate some modulation methods, which have been defined based on Elliptical Modulation Scheme, namely are Eccentricity Shift Keying (ESK), Inclination Angle Shift Keying (IASK) and Elliptical Phase Shift Keying (EPSK). In this paper, signal characteristics of these three modulation schemes and effect of eccentricity to the waveforms have been demonstrated and analysed, through observing real signals generated by using DSPs, both in time-domain and frequency-domain; performances of IASK, 4-EPSK and 8-EPSK, as three modulation methods capable of 1-bit, 2-bit and 3-bit information transmission under the same carrier frequency respectively, have been evaluated through Matlab simulation in terms of BER, advantages over existing modulation schemes suggested that newly proposed modulation schemes can contribute to the improvement of wide-band wireless communication systems.
