Distributed network time synchronization using pseudo noise code
In recent years, distributed network systems have been studied in order to yield a higher data rate. However, performance of a distributed network degrades drastically when all nodes are not properly synchronized. This thesis discusses the practical issues involved in existing distributed network synchronization algorithms, and proposes an alternative solution for time synchronization in distributed networks using a pseudo noise (PN) code. The proposed algorithm has the following advantages over the existing algorithm: (1) increased time width of the pulseshaping filter, i.e., narrowband waveform-shaping filter; (2) ability to work under a lower signalto- noise ratio; (3) capability of reaching a steady state with fewer iterations; and (4) lower steady-state error and fewer samples required per one update interval. Chapter 6 will elaborate and explain these advantages. Simulation results will show the effectiveness of the algorithm proposed and the advantages of the proposed algorithm over existing algorithms.
