(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,...
whereasFDMDVuses differentialPSK. CoherentPSKis more robust against bit errors than differentialPSK. This mode has 14 subcarriers, but it's actually 7 75bd subcarriers duplicated to form the full 14, so there is strong redundancy. The entire system runs at 700bit/s, using the 700bit/sCodec...
