Phase-Shift Keying (PSK)
Definition - What does Phase-Shift Keying (PSK) mean?
PSK is typically applied in wireless local area networks (WLAN), Bluetooth technology and radio frequency identification (RFID) standards used in biometric passport and contactless payment systems.
Techopedia explains Phase-Shift Keying (PSK)
Two common PSK types are as follows:
- Quadrature Phase-Shift Keying (QPSK): Uses four phases to encode two bits per symbol.
- Binary Phase-Shift Keying (BPSK): Simplest PSK type. Uses two phases separated by 180 degrees.
