Abstract

PURPOSE:To realize an exact digital transmission system, by correcting in advance a distance delay portion of a leased circuit to a transmitting place and a receiving place, in a communication control room, and also taking synchronization by correcting a position, in a mobile station side. CONSTITUTION:In case when the bit synchronization of fixed stations 2, 3 and mobile stations 4, 5 and 6 is corrected prior to start of communication, at first, a delay time to the fixed transmitting station 2 from a communication control room 1 is denoted as t1 and a delay time to the communication control room 1 from the fixed receiving station 3 is denoted as t6, and in this case, a fixed delay correction of t1+t6 is executed by a controlling circuit in the fixed station, and a bit and a frame synchronizing signal are transmitted. On the other hand, each mobile station 4, 5 and 6 executes the initial synchronization matching by this synchronizing signal, and after that, estimates a distance between a position of its own station and the fixed receiving station 3, corrects a delay in accordance with this distance, and decides a transmission timing.
