Abstract

PURPOSE:To establish economical time sharing multiple connection system communication use terminal station unit, by storing and processing the part excluding the fixed or semi-fixed code of the burst of input modulator and output of demodulator to the memory circuit. CONSTITUTION:In a ground station of satellite communication, the signal input to the terminal 3 is converted at the conversion circuit 29 being the digital signal of a given form. This signal is once stored in the memory circuit 30 together with the digital signal corresponding to the signal fed to other input terminals 3a, 3b under the control of the processor 31. The signal stored in the circuit 30 is added with the fixed code and semi-fixed control signal for the synchronism processed with require processing and read out in high speed at the unit 31 to form the burst and output is made after digital modulation 9. Further, the reception signal is in digital demodulation 12 and stored in the memory circuit 33 under the control of the processor 33. The digital signal stored in the circuit 32 is read out with required processing at the unit 33 and given to the conversion circuit 34, and it is converted into the signal form corresponding to the ground station for output.
