Proposal and evaluation of 8-ary elliptical phase shift keying

Some modulation schemes with the general name of elliptical modulation schemes, have been proposed and generally evaluated through computer simulations in our previous works, namely eccentricity shift keying (ESK), inclination angle shift keying (IASK) and elliptical phase shift keying (EPSK). This paper aims to propose and evaluate 8-ary elliptical phase shift keying (8-EPSK), a new modulation scheme with 3-bit information transmission capability. In the paper, 8-EPSK was defined mathematically at first; it was then evaluated mathematically and by computer simulation in terms of BER, along with comparison to 8PSK. Both analysis results and simulation results showed that 8-EPSK outperforms 8PSK.
