The 8PSK (8 Phase Shift Keying) modulation scheme is a digital modulation technique that alters the phase of the carrier signal to represent data. In this scheme, the carrier signal is divided into eight different phases, each representing a unique set of bits. This allows for the transmission of three bits per symbol, enhancing the data rate. However, the increased phase states also make 8PSK more susceptible to noise and interference, requiring a higher signal-to-noise ratio for accurate data transmission. Despite this, 8PSK is widely used in high-speed wireless and satellite communication due to its efficient use of bandwidth.
