| 摘要 |
The present invention provides a load impedance defect detection system for use in a CDMA base station transmitter including a base band signal generation unit (101) and a reflected signal monitor (106) for detecting a reflected signal. A CPICH power detector (111) detects a CPICH power from the reflected signal obtained from the reflected signal monitor. A return-loss determination unit (112) determines a return-loss based on a difference between a CPICH power value detected by the CPICH power detector and a CPICH transmission power set value (113) provided by the base band signal generation unit, and determines that there is a load impedance defect when the return-loss exceeds a predetermined threshold value. |
