TWO-WAY MULTIPLEX TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To perform a delay control so that no collision is caused by controlling signal transmitting time from each slave station and to extend data transmission capacity as a whole in a two-way multiplex transmission system, to perform two-way communication by using a TDM-TDMA control system. SOLUTION: Measurement of transmission delays to control transmission timing of each slave station is successively and repeatedly performed for each slave station and a frame interval of one transmission frame or more is provided between the measurement of a certain slave station and that of the next slave station. An rise data are and/or a fall data area are extended instead of a delay measuring area in a transmission frame to which no measurement of the transmission delay is performed.
