This technology is integral to Wi-Fi networks, cellular telephony, digital television broadcasting, and satellite uplinks. Phase shift keying definition describes a digital modulation scheme where the phase of a continuous wave carrier signal is varied to represent binary data.
Phase Shift Keying in Wi-Fi and Cellular Applications
The complexity of the demodulation process can increase costs, and the technique requires precise timing synchronization. Unlike amplitude or frequency modulation, this technique encodes information solely through intentional shifts in the signal’s timing position.
Engineers favor it when consistent, high-quality data transmission is non-negotiable. Fundamental Mechanics of Phase Encoding At its core, phase shift keying relies on the synchronization between a transmitter and a receiver.
