About this document
QPSK Modulation and Demodulation Guide by pankaj singh is a document available to read on EtoBox.
The document describes an experiment on Quadrature Phase Shift Keying (QPSK) modulation and demodulation. QPSK modulation encodes digital data into phases of a carrier wave, transmitting two bits per change in phase. It uses a modulator that splits even and odd bits, multiplies them with a carrier that is in or out of phase by 90 degrees, and sums the signals. The QPSK demodulator uses two detectors to simultaneously recover the two BPSK signals and convert them back to the original digital data bits. The e
