A Novel 32-Point Modulation Scheme of 6PolSK-QPSK Signal
TL;DR: In this paper , a novel encoding rule and compensation scheme for 32-Point 6PolSK-QPSK modulation by classifying symbols was proposed, and the simulation results show that the error performance of 2.6 dB and 8.7 dB are improved for unrevised and revised data transmission, compared with the 32-point 6Pol SK-QPK signal scheme obtained by rotating PM-QPsK.
