DEVICE AND METHOD FOR MEASURING ANTENNA ISOLATION

摘要

A device for measuring antenna isolation, which can measure isolation between a link antenna for receiving a signal from a base station and a service antenna for transmitting a signal to a mobile station, comprises: a delay unit for receiving an antenna receiving signal, which is received through the link antenna and digitally converted, and delaying the received antenna receiving signal by units of a preset sample; a correlation unit for receiving the antenna receiving signal and performing a correlation operation between the received antenna receiving signal and a delay signal delayed by the delay unit; and a control unit for determining the isolation between the link antenna and the service antenna based on the size of a cross-correlation value generated by the correlation operation of the correlation unit.
