QPSK MATLAB Simulink Receiver and Transmitter

QPSK MATLAB Simulink receiver and transmitter implementation using Quadrature Phase Shift Keying modulation technique.

In this documentation, I will further expand on the implementation of QPSK MATLAB Simulink receivers and transmitters. QPSK (Quadrature Phase Shift Keying) is a digital modulation technique that represents digital data by shifting the phase of orthogonal carrier signals. When designing QPSK receivers and transmitters using MATLAB Simulink, we can leverage this powerful tool to simulate and analyze signal transmission processes. Through MATLAB Simulink implementation, we can build complete communication systems including Bit Error Rate (BER) testing modules, channel models, and modem components. The implementation typically involves using Simulink blocks such as QPSK Modulator and Demodulator blocks, AWGN Channel blocks for noise simulation, and Error Rate Calculation blocks for performance analysis. This approach allows us to better understand and optimize QPSK system performance by adjusting parameters like carrier frequency, symbol rate, and signal-to-noise ratio through graphical block diagrams rather than traditional code-based programming.
