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.
