The BPSK Demodulator Baseband block demodulates a signal that was modulated using the binary phase shift keying method. The input is a baseband representation of the modulated signal. This block accepts a scalar or column vector input signal. The input signal must be a discrete-time complex signa...

BPSK Demodulator BPSK is a Bi-phase modulation method, where the zeroes and ones in a binary message are comprised by two dissimilar phase values. The base functions are impertinent to each other. The modulation is attained by varying the phase of the sinusoidal signal based on the message ...

One of the essential components of a coherent demodulator associated therewith is adapted to regenerate the carrier wave, i.e. generate a periodic signal of a constant phase, having a frequency of the same frequency as the modulated signal. The generated signal, which is called the "regenerated...
