Binary Phase Shift Keying describes a technique modulating a sinoid carrier frequency by changing the ''phase'' between two defined states: 0° and 180°. The amplitude of the modulated signal remains constant, therefore this is called phase shift keying. Each phase state corresponds to a symbol, as there are only two states we have here only two possible symbols. |
