  • Abstract
    We modify a 2nd-order digital phase-locked loop (PLL) with additional frequency-offset compensation and pilot-symbol aided cycle slip recovery modules, and show that the modified 2nd-order PLL can successfully recover the carrier phase for a 16-QAM coherent detection system with a frequency offset up to 10% of the symbol rate.
