DISTRIBUTED SYNCHRONIZATION EXECUTION METHOD INCLUDING SMALL OVERHEAD IN AN AD-HOC NETWORK SYSTEM

摘要

PURPOSE: A distributed synchronization execution method is provided to execute in synchronization by considering the delay of the radio wave according to the distance between the nodes.;CONSTITUTION: Signals including a reception point conversion period are received through a plurality of nodes(S600). A reception point receiving the signal through a plurality of the nodes is converted within the reception point conversion section in order to include a CP(Cyclic Prefix) section(S605). An FFT(Fast Fourier Transform) starting point is converted based on the converted reception point(S610). Each transmission point of the nodes based on the difference of value between the set FFT starting point and the converted FFT starting point is converted(S615).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S600) Receive a signal; (S605) Convert a reception point; (S610) Convert an FFT starting point; (S615) Convert the reference point of a transmission timing
