MATLAB provides a powerful platform for implementing and simulating digitalmunication systems. The code snippet provided in the previous section demonstrates how QPSK modulation and demodulation can be implemented using MATLAB. The code generates a random QPSK modulated signal, displays the signal in a ...
The comm.QPSKModulator object modulates a signal using the quadrature phase shift keying (QPSK) method.
