PROBLEM TO BE SOLVED: To provide a transmission system that can reduce deterioration in Noise Figure (NF) due to correction of a transmission loss difference. SOLUTION: A master station 30, slave stations 34-1, 34-2, 34-n and a repeater 32 that composites signals received from the slave stations and transmits the composited signal to the master station are used for signal transmission. The repeater is provided with an attenuator 54 or the like that corrects differences between slave stations in transmission losses between the slave stations and the repeater. Since the signal can immediately be composited after the attenuation, the deterioration in the NF can be reduced. |
