What Does PSK Stand For?

PSK stands for Phase Shift Keyed

PSK, or Phase Shift Keyed, is a modulation scheme used in digital communication systems where data is transmitted by varying the phase of a carrier signal. In PSK, each phase shift represents a unique symbol that corresponds to a specific data value, allowing efficient use of bandwidth and improved resistance to noise. Common variants of PSK include Binary PSK (BPSK) and Quadrature PSK (QPSK), each offering different balances between complexity and data rate. PSK is widely utilized in applications such as satellite communication, wireless networks, and digital broadcasting.
