Modulation recognition of composite modulation signal based on two-fold digital receiver and goodness of fit test

2021 · 2021 IEEE International Conference on Electronic Technology, Communication and Information (ICETCI)

Aiming at the modulation recognition problem of mixed signal set {BPSK, QPSK, BPSK-FM, QPSK-FM} with unknown parameters, this paper proposes a modulation recognition algorithm based on two-fold PLL (phase locked loop) and goodness of fit …
