WebNov 20, 2024 · Decoding a BPSK Signal. Binary phase shift keyring or BPSK is the simplest form of digital phase modulation. Depending on the phase of the signal, the hardware or software decodes a zero or one. In this exercise dervied from the DoD Hack-A-Sat challenge, Phasor, you will decode a BPSK signal using GNU Radio to reveal a flag. WebApr 7, 2024 · RadioML2016.10a : this dataset belongs to a public open -source dataset for automatic modulation classification, using GNU Radio to synthesize I/Q samples. The dataset contains 11 modulation types, including BPSK, QPSK, 8PSK, 16QAM, 64QAM, BFSK, CPFSK, and PAM4 for digital modulation. And WBFM, AM-SSB, and AM-DSB …
WebIn the case of BPSK, each symbol represents one bit, and therefore the baud rate equals the bit rate. So, if our sample rate is 32 kHz and sps = 8, then our data rate is 4 kb/second. The output of constellation modulator block has converted our digital data stream into a baseband train of SRRC-shaped pulses scaled by the symbol values.
