BPSK (Binary Phase Shift Keying)

BPSK (Binary Phase Shift Keying) is a digital communication method where information is transmitted using two distinct phases of a carrier wave, typically representing binary 0s and 1s. Essentially, it alters the wave's phase by 180 degrees to indicate each bit. When the phase is as original, it might represent a 0; when shifted, it represents a 1. This technique is simple, robust against noise, and widely used in wireless and satellite communications to efficiently send digital data over radio waves.
