8PSK (8-ary Phase Shift Keying)
8-PSK encodes three bits per symbol by selecting one of eight phases of the carrier wave, providing higher spectral efficiency than QPSK at the cost of needing a higher signal-to-noise ratio. 8-PSK is used in EDGE for 2.75G mobile data, in some satellite return channels, and in other systems where the noise budget allows.
