How does 8PSK work?

8PSK modulation means that the upper sideband signals of the two first-order sidebands suppressed by the carrier , are averagely divided into 8 phases and then synthesized. As shown in Figure 2, the upper and lower two signals are orthogonal to each other, but the amplitude is different.

How many bits is 8PSK?

8 Phase-Shift Keying (8PSK) is a form of phase modulation with eight phase states located at 0, π, +/-(π/4), +/-(π/2) and +/-(3π/4) radians in the IQ plane. Each symbol carries log2(8) = 3 bits of information. A sample 8PSK constellation is shown below.
