WebThis is a basic block diagram for a QPSK modulator. First, the digital data stream is processed so that two consecutive bits become two parallel bits. Both of these bits will be transmitted simultaneously; in other words, as mentioned in this page, QPSK allows one symbol to transfer two bits. The local oscillator generates the carrier sinusoid.
