QPSK Bit Synchronization Source Code Implementation

This document presents QPSK bit synchronization source code implementation, which incorporates functionality for modulation/demodulation and channel noise addition. QPSK (Quadrature Phase Shift Keying) represents a widely used digital modulation technique in communication systems. The modulation/demodulation process involves converting digital signals to analog format for transmission, then reconverting received analog signals back to digital format for decoding. Channel noise addition simulates signal degradation during transmission caused by channel interference and noise. The QPSK bit synchronization source code ensures accurate modulation/demodulation processing and effective noise handling during communication by implementing carrier recovery algorithms, timing synchronization routines, and noise modeling functions. Key implementation components include I/Q signal processing, phase detection algorithms, and additive white Gaussian noise (AWGN) generation for realistic channel simulation.
