P.25 emergency signal reception using captured signals or software-defined
Use cyclostationary feature detection to distinguish signals with different modulation schemes, including P25 signals [ 1]. It defines four cases of signals: noise only, C4FM, CQPSK, and one arbitrary type. The example applies the detection algorithm to signals with different SNR values, and to a captured real-world P25 signal, and then classifies the signals as one of the four types. Graphical results show that the detection algorithm succeeds in all the cases.
