Abstract

PURPOSE:To realize a high-speed measurement in a simple constitution by storing the whole or part of the local transmission burst into the buffer memory in sequence and then giving the comparison and detection between the contents of the buffer memory and the local reception burst received after the circuit delay time to measure the error rate. CONSTITUTION:Transmission burst (a) sent from time-division multiple access (TDMA) transmission part 4 which transmits transmission data 5 is applied to modulator 6, and transmission carrier d sent from modulator 6 is sent to satellite repeater 7. The reception carrier (e) from repeater 7 is received and demodulated at demodulator 8 to deliver reception burst (b). And reception data 10 is delivered from TDMA reception part 9. For measurement of the error rate of the TDMA circuit in the real working state, burst (a) sent from part 4 is stored in buffer memory 11 sequentially. And a comprison is given between the contents written into memory 11 after the both-way delay time and burst (b) which has just arrived at comparator 12. And error pulse (c) is delivered when no coincidence is obtained through the comparison.
