CDMA SIGNAL ANALYSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To enable a channel where an abnormal event has occurred to be grasped at a glance from a code domain power characteristic graphically indicated in an indicator.

SOLUTION: Chip data are prepared from a measured signal (10). The chip data are reversely diffused to be outputted as symbol data of each channel (22). A code domain power of each channel is calculated by using the symbol data of each channel (24). A domain power characteristic (31) is indicated in an indicator (29). A code domain error of each channel is calculated (25). A code domain error exceeding a threshold preset in the code domain errors of the channels is designated (28). The code domain power of the channel is emphasized and indicated (29) as corresponding to the channel of the code domain error exceeding the threshold within the code domain powers of the channels in the code domain power characteristic.
