(1) See preshared keys.

(2) (Phase Shift Keying) A digital modulation technique that uses two phases for a 0 or 1. Also called "binary PSK" (BPSK), it is the most basic form of phase shift keying. For example, quadrature PSK (QPSK) uses four phase shifts for each two bits of input. See phase modulation, QAM and DPSK.

Phase Shift Keying

PSK is a simple technique that uses two phases to represent 0 and 1.

Quadrature PSK

QPSK uses four phases 90 degrees apart to represent four values in each two bits (0-4) of input.
