A new method of demodulation for 16APSK/32APSK

16APSK and 32APSK, which are adopted by DVB-S2, can improve spectral efficiency. In order to reduce BER, the receiver will use demodulation method with good performance and low computation complexity. Based on the existing several demodulation methods, this paper presents a new demodulation method with practical value, and compares BER performance with several other existing demodulation methods through simulations. The simulation results verify the validity of the proposed methods of demodulation.
