Abstract
Disclosed is a binary phase shift key (BPSK) demodulating device using a phase shifter and a method thereof. The BPSK demodulating device includes an I signal generator to generate an in-phase (I) signal from a received BPSK signal, a Q signal generator to generate a quadrature-phase (Q) signal from the received BPSK signal, using a plurality of phase shifters, an oscillator to generate a first signal to separate a baseband signal, and a determining unit to determine a transmission phase angle based on the I signal and the Q signal.
