SYNCHRONIZATION SIGNAL CREATION APPARATUS CAPABLE OF STABLY PROVIDING A SYNCHRONIZATION SIGNAL TO A BASE STATION OR A COMMUNICATION APPARATUS

摘要

PURPOSE: A synchronization signal creation apparatus is provided to create a synchronization signal by using a communication signal except for a first communication signal.;CONSTITUTION: A first synchronization signal output unit(12) extracts a first synchronization signal from a first communication signal. A second synchronization signal output unit(24) extracts a second synchronization single from a second communication signal which is different from the first communication signal. A delay time measurement unit(16) measures a time difference between the first and the second synchronization signal. A signal delaying unit(17) creates the first synchronization signal by delaying the second synchronization signal. The signal delaying unit outputs the first synchronization signal from a network synchronization signal.;COPYRIGHT KIPO 2012
