A METHOD CHECKING TRANSFERRING AND RECIEVING CHANNEL IN DAISY CHAIN WCDMA SYSTEM

摘要

A transmitting/receiving path verification method in a WCDMA(Wideband Code Division Multiple Access) system where transceiver boards are connected in serial is provided to be capable of simultaneously measuring bit error rates of each transceiver board connected in serial by a cable, therefore characteristics of paths are analyzed more exactly. Verification standard data are stored in a jig board and each transceiver board of a system(S910-S950). The jig board outputs transmission verification data to sequentially transmit the data to a lower board from an upper board of the transceiver boards which are connected in serial(S961,S962). The respective transceiver boards compare the received transmission verification data with the pre-stored verification standard data to measure errors(S963,S970).
