Abstract :
The basic digital frequency-locked loop (DFLL) with a quadri-correlator frequency detector is analyzed. Detailed derivations of its convergence characteristic and steady state mean-squared error (MSE) are given for BPSK signaling with known and unknown transmitted symbols. Simulation results for the known symbol case are given, which agree very well with analysis
