Abstract:
1. A receiving portion monitoring system in a wireless base station system, comprising: receiving and amplifying means for amplifying a received signal; and wireless base station means for demodulating a signal output from said receiving and amplifying means and for detecting a fault in said receiving and amplifying means on the basis of the demodulated signal, wherein said receiving and amplifying means includes a pilot signal generation portion which generates a pilot signal for detection of a fault, and an amplifier which amplifies the received signal and the pilot signal, and said wireless base station means includes a wireless portion which demodulates a signal output from said amplifier and computes an RSCP value and a BER value from the demodulated signal, a detection portion which computes a feeder loss and an NF value between said receiving and amplifying means and said wireless base station means from the computed RSCP and BER values, and an RTWP processing portion which outputs an RTWP value including a value relating to the NF value detected by said detection portion.
