| Abstract: | To investigate the modulation recognition of Phase Shift Keying (PSK) signals widely used in satellite Communication, such as pi/4-QPSK and 8-PSK , an algorithm for modulation recognition based on higher-order cumulants of signal difference is proposed. The modulation of pi/4-QPSK and 8PSK will be recognized based on four and eight order cumulants of signal difference. The efficiency of the algorithm is proved in theory. Computer simulations show that the proposed recognition algorithm is high in performance. |
