MATLAB Implementation of QPSK Modulation and Demodulation
This MATLAB implementation of QPSK modulation and demodulation assumes the receiver has achieved carrier synchronization and bit synchronization. Key challenges in blind signal demodulation include carrier synchronization (typically implemented using Costas loop, though code is not provided here), bit synchronization (commonly addressed with Gardner algorithm, code not included), and frame synchronization.

Simulation of QPSK Modulation and Demodulation in Simulink Model
This Simulink model simulates QPSK modulation and demodulation processes, where a square root raised cosine (SRRC) pulse-shaped signal is modulated and fed into the demodulator. The received signal undergoes demodulation followed by matched filtering and downsampling operations in the detector module, demonstrating symbol timing offset effects through phase adjustment.
