RADIO FREQUENCY REPEATER AND ISOLATION DETECTING METHOD OF THE SAME

摘要

A method for measuring a degree of isolation of a radio frequency (RF) repeater according to an embodiment of the present invention includes: (a) generating sampling data by sampling an analog signal based on at least one between downlink signal and uplink signal received in an RF repeater; (b) setting the sampled data included in a first time period as first sampled data and setting data included in a second time period which is made by delaying the first time period with a predetermined delay time as second sampled data; (c) calculating an auto-correlation coefficient of the first sampled data and calculating a cross-correlation coefficient of the first and second sampled data; and (d) calculating a degree of isolation based on the auto-correlation coefficient and the cross-correlation coefficient.
