TIME DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEM, SIGNAL RECEPTION METHOD IN THE TIME DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEM AND CENTER EQUIPMENT USED IN THE TIME DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To extend a fluctuation allowable period at the receiving of fluctuation channel signals from synchronization non-established subscriber' s equipment, without pressing the reception period of fixed channel signals from synchronization established subscriber's equipment and to extend a maximum transmission distance between a center equipment and the subscriber's equipment. ;SOLUTION: This center equipment 2 for performing time division multiple access communication with the plural subscriber's equipment 4-1 to 4-N is provided with a channel reception part 14 for receiving signals for synchronization establishment from the subscriber's equipment 4-i (where i=1 to N), for which a reception timing can fluctuate as the fluctuation channel signals and receiving communication signals received at a fixed timing from the synchronization established subscriber's equipment 4-i as the fixed channel signals and a control part 26-3 for controlling the reception processing of the channel reception part 14, so as to receive the fluctuation channel signals in the reception period of the fixed channel signals.;COPYRIGHT: (C)1999,JPO
