<p>A load impedance faulty detecting system in a base station transmitter of CDMA system comprising a baseband signal generating part (101) and a reflected signal monitor part (106) that detects a reflected signal. A CPICH power determining part (111) determines a CPICH power from the reflected signal acquired from the reflected signal monitor part. A return loss determining part (112) determines a return loss from a difference between the CPICH power value determined by the CPICH power determining part and the CPICH transmission power set value (113) applied from the baseband signal generating part, and detects a load impedance faulty when thereturn loss exceeds a predetermined threshold value. ® KIPO & WIPO 2007</p> |
