WebCONCEPT OF BINARY PHASE SHIFT KEYING: Binary Phase Shit Keying (BPSK) Principle o BPSK In binary phase shit keying (BPSK), binary symbol ‘1’ and ‘0’ modulate the phase of the carrier. Let the carrier be, ‘A’ represents peak value of sinusoidal carrier. In the standard 1Ω load register, the power dissipated will be Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave). The modulation is accomplished by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and Bluetooth communication.
