What is psk?

PSK stands for Phase Shift Keying, a type of digital modulation technique used in telecommunications to encode data onto radio waves. In PSK, the phase of the carrier signal is varied in order to represent different symbols or bits of information. The most common types of PSK are Binary PSK (BPSK), Quadrature PSK (QPSK), and Differential PSK (DPSK).

PSK is often used in digital communication systems such as Wi-Fi, Bluetooth, and mobile networks. It is known for its efficiency and robustness, making it a popular choice for transmitting data over long distances with minimal errors. PSK modulation is also relatively simple to implement and has good spectral efficiency compared to other modulation techniques.
