Simulated OAM-carrying BPSK signals waveform. (a) The first original BPSK signal. (b) The second original BPSK signal. (c) The demodulated signal at the center frequency and each harmonic frequency (solid line) and the first input original BPSK signal (dash line). (d) The demodulated signal at the center frequency and each harmonic frequency (solid line) and the second input original BPSK signal (dash line).
