PROBLEM TO BE SOLVED: To reduce a mounting area and manufacturing cost while suppressing influence of overflow distortion in an A/D converter.SOLUTION: A first A/D converter in an integration/relay station apparatus performs analog/digital conversion of an integrated uplink signal, outputs the A/D converted signal to a switching part and a second A/D converter performs analog/digital conversion of an attenuated integrated uplink signal and outputs the A/D converted signal to the switching part. A distortion detection part detects a data section in which distortion caused by a signal level of the integrated uplink signal inputted to the first A/D converter may be generated in the first A/D converter on the basis of output data of the second A/D converter, the switching part switches the output data of the first A/D converter in the detected data section into the output data of the second A/D converter matching the signal level, and a transmission part relays and transmits the output data of the first A/D converter or the second A/D converter which is outputted by the switching part to a master station apparatus. |
