BPSK and QPSK Modulation Techniques by Fyhh is a document available to read on EtoBox.
Phase Shift Keying (PSK) is a digital modulation technique that transmits data by varying the phase of the carrier wave in accordance with the digital modulating signal. Binary PSK (BPSK) uses two phases that are 180 degrees out of phase, representing 1 and 0. Quadrature PSK (QPSK) modulates two bits at a time onto the carrier, using four phases that are 90 degrees apart. At the transmitter, the message signal is converted to BPSK or QPSK and used to modulate the carrier wave. At the receiver, coherent de
