High precision frequency synchronization via IP networks

<p>This  report  is  a  part  of  a  master  thesis  project  done  at  Ericsson  Linköping  incooperation with Linköpings Tekniska Högskola (LiTH). This project is divided intwo different parts.  The first part is to create a measurement node that collectsand processes data from network time protocol servers.   It is used to determinethe  quality  of  the  IP  network  at  the  node  and  detect  potential  defects  on  usedtimeservers or nodes on the networks.The second assignment is to analyze the collected data and further improve theexisting synchronization algorithm.  Ip communication is not designed to be timecritical and therefore the NTP protocol needs to be complemented with additionalsignal processing to achieve required accuracy.  Real time requirements limit thecomputational complexity of the signal processing algorithm.</p>
