Abstract


Quadrature Phase-Shift Keying (QPSK) modulation technique is one of the most widely used modulation scheme in modern digital communication system; it provides high performance on bandwidth efficiency. In this paper, the model of QPSK modulator and demodulator has been simulated using MATLAB Simulink.
