BPSK is a type of digital modulation that stands for Binary Phase Shift Keying.
(BPSK ) is a technique that conveys data by changing the phase of a constant frequency carrier wave according to the binary information signal. BPSK uses two phases, 0° and 180°, to represent logic 0 and logic 1, respectively. BPSK is the simplest and most robust form of PSK, which is phase shift keying. BPSK has a low spectral efficiency but a high tolerance to noise and interference. BPSK is widely used in various wireless standards such as CDMA, WiMAX, WLAN, satellite, DVB, and cable modem.
Some of the advantages of BPSK are:
• It is easy to implement and demodulate
• It has a low bit error rate
• It can operate at low signal-to-noise ratios
• It can transmit over long distances
Some of the disadvantages of BPSK are:
• It has a low data rate
• It requires accurate synchronization between the transmitter and the receiver
• It is susceptible to phase ambiguity and distortion
