Abstract: Aspects of the present application provide methods and devices for using a combined quadrature amplitude modulation (QAM) and amplitude phase shift keying (APSK) modulation scheme in a hybrid modulation form in order to benefit from advantages of each respective modulation scheme. The proposed hybrid modulation scheme is less sensitive to phase noise and has lower peak-to-average power ratio (PAPR) than QAM and has very similar performance as QAM with respect to additive white guassian noise (AWGN).
