PROBLEM TO BE SOLVED: To calculate NF(Noise Figure) in an outdoor receiving amplifier and loss in the feeder automatically and make an accurate RTWP(Received Total Wideband Power) report. SOLUTION: A pilot signal generated within the outdoor receiving amplifier 3 is decoded in a wireless section 11 to calculate RSCP(Received Signal Code Power) and BER(Bit Error Rate), and the feeder loss and NF are calculated by the detection section 12 based on the RSCP and BER within a wireless base stations system 5. In addition, in an RTWP processing section 13 reports the received input level with the above NF (RTWP value) to a higher system. |
