PROBLEM TO BE SOLVED: To provide a delay correction system capable of performing delay correction for turning transmission timing of downlink transmission signals to the same timing in each radio equipment without making an equipment configuration complicated, to provide a radio base station apparatus, to provide a delay correction circuit, and to provide a delay correction method.;SOLUTION: In the delay correction system 1 wherein AMPs 1-1 to 1-n and 2-1 to 2-N provided with a synchronization detection part for detecting synchronizing signals and the base station apparatus 10 provided with a synchronizing signal output part for outputting the synchronizing signals are connected by an optical line, the base station apparatus 10 outputs the synchronizing signals to the AMPs 1-1 to 1-n, clocks the time required for the reciprocation of the synchronizing signals as a delay amount, and delays output timing of output signals for each of the AMPs 1-1 to 1-n on the basis of the clocked delay amount.;COPYRIGHT: (C)2010,JPO&INPIT
