摘要: In a TDMA system comprising plurality of earth stations communicable with one another by the use carrier waves through transponder satellite which has an available electric power level, bursts carried are individually and flexibly controlled in accordance burst time plan so that selected ones have on total level does not exceed at any time. The therefore may different levels dependency upon scales stations, traffics bursts, receiving conditions conditions. can be transmitted or received frequency hopping. Such control is out each station combination attenuator (67) attenuation circuit (71) operated plan.
