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.

8PSK in context

To place 8PSK in the wider telecom-security picture, review QPSK, SNR, Carrier Aggregation, 1G, 6G and EDGE.
