2024年5月15日 · Binary Phase Shift Keying (BPSK) is a modulation technique employed in communication systems to transmit information via a communication channel. In BPSK the carrier signal is modified by altering its phase by 180 degrees, for each symbol. A phase shift of 180 degrees denotes a binary 0 while no phase shift represents a binary 1.
Phase-shift keying - Wikipedia
Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency 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.
