Synchronization - Part II — Lesson 2

This lesson covers the concept of synchronization in networks, focusing on open loop and closed loop synchronization. It delves into the unique word detection part of synchronization in a burst and network synchronization. The lesson also explains how transmitters pre-correct to ensure the burst reaches the receiver at the right time. It further discusses the impact of Doppler on frequency domain and how to correct for errors in time source or frequency source. The lesson also covers the concept of time reference and how it differs between transmitter and receiver. It concludes with a detailed explanation of TDMA synchronization, initial acquisition, steady state synchronization, and how to select guard time.
