Demodulator Design: We do coherent demodulation of the BPSK signal at the receiver. Coherent demodulation requires the received signal to be multiplied with the carrier having the same frequency and phase as at the transmitter. The phase synchronization is normally achieved using Phase Locked Loop (P...
means for detecting the BPSK signal from the FM signal, said means including circuitry for radio-frequency reception, FM demodulation, bandpass filtering to select the BPSK signal resulting from FM demodulation, and hardlimiting the selected BPSK signal, and ...
12.A method of low power BPSK demodulation, comprising:mixing, by a first mixer, a BPSK signal and a carrier signal to form a mixed signal;filtering, by a first low pass filter, the mixed signal to form a data signal;mixing, by a second mixer, the data signal and the carrier signal...
