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.
