8-PSK (8-Phase Shift Keying)

A signal modulation technique that involves eight levels of phase shift

and, therefore, supports three bits per symbol. 8-PSK is specified in Enhanced General Packet Radio Service (EGPRS), the packet-switched transmission mode of Enhanced Data rates for GSM Evolution

(EDGE), a 2.5G cellular radio standard. See also 2.5G, bit, cellular radio, EDGE, EGPRS, modulation, phase, PSK, signal, and symbol.
