    摘要: A transmit phase control system of synchronization burst is disclosed for use in a SDMA/TDMA satellite communication system in which a phase error between a synchronization burst transmitted from an earth station and a synchronization window, assigned as a time slot on a satellite for returning the synchronization burst, is measured and the transmit phase of the synchronization burst is controlled based on the measured value. Phase error measurement is achieved a plurality of times in connection with the received synchronization burst of each station, and a decided phase error is derived based on the measured value obtained by the plurality of measurements. The transmit phase of the synchronization burst is then controlled in accordance with the decided phase error. Further, the phase error decision is achieved at every 1/n (n being an integer larger than 1) round trip and the present synchronization burst is transmitted with its transmit phase corrected corresponding to a value that is the sum of the phase corrected value of the n preceding phase correction instants subtracted from the decided phase error at the present instant.

    摘要: A transmission unit transmits the identical transmitting information including a communication number information. A communication number counting unit increments the communication number information every time the identical transmitting information is transmitted, sets the communication number information which is greater than the incremented last communication number information to an initial communication number information when a renewed transmitting information is transmitted, and increments the initial communication number every time the renewed transmitting information is transmitted. An information discrimination unit discriminates whether or not a receiving transmission information conforms with a registration transmitting information. A communication number information comparison unit compares a receiving communication number information with a registration communication number information. A control unit adds a predetermined value to the receiving communication number information when the receiving transmission information conforms with the registration transmitting information and the received communication number information is greater than the registration communication number information.

    摘要: An acquisition system for the SDMA/TDMA satellite communication system is disclosed in which a synchronization signal receiving time slot and a plurality of data signal receiving time slots, for communication between predetermined groups of earth stations and between the earth stations of each group, are sequentially provided at the satellite based on timing signal in the satellite. An acquisition signal having a plurality of signal burst portions is transmitted from the earth station, with its transmit time slot being shifted in a first sweep mode until one part of the acquisition signal is received by said transmitting earth station. At that time the transmit time slot is shifted in a second sweep mode, whereby a control is made to obtain synchronization of the earth station with the satellite so that the plurality of burst portions in the acquisition signal may be properly communicated to the predetermined groups.Further, an acquisition control is shown to be effectively achieved in the case where the SN ratio of the received acquisition signal is extremely deteriorated or where it is necessary to prevent disturbing another earth station of the same group of earth stations which has already accessed the satellite.
