摘要

There is provided a propagation delay time adjustment method for adjusting the propagation delay time occurring within a reception circuit for each channel of a center node device configuring a 1-to-N communications system in which communication is performed between the center node device and N (N being an integer of 2 or more) individual edge node devices using a Synchronous Code Division Multiplexing method, the center node device comprising a main control section, and each of the edge node devices comprising an auxiliary control section that controls the propagation delay time in cooperation with the main control section, the transmission delay time adjustment method comprising: transmission permission signal transmitting; transmission controlling; reception phase controlling; reception validity determining; optimum reception phase determining; and reception phase setting in which the main control section sets the optimum reception phase as the reception phase for the reception circuit.
