Complete QPSK demodulation implementation including carrier synchronization using decision-directed feedback and bit synchronization employing early-late gate algorithm, with MATLAB code descriptions.
Simulation of bit timing recovery in baseband digital communications using Gardner algorithm without interpolation, employing SRRC for pulse shaping, implementing simplified alfa/1-alfa low-pass filtering instead of PI loop filter, and utilizing straightforward NCO adjustment methods.
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.
This bit synchronization program utilizes early-late gate sampling results to achieve bit synchronization through a phase error detector, loop filter, and digitally controlled oscillator (DCO) implementation.
