Abstract

We study the frequency offset correction for high-speed laser communication system with Pulse Position Modulation (PPM) and Superconducting Nano-wire Single Photon Detector (SNSPD). In particular, we consider that the dead time is longer than the symbol time. We consider an inter-symbol guard time-based sliding window synchronization algorithm, and evaluate its performance under various window sizes, sampling rates, and frequency offsets. These studies provide a design guideline for building practical communication system.
