Abstract
This paper suggests the adaptive multi-feedback filter system which, among a number of adaptive feedback filters in the wireless repeater system, applies the most appropriate feedback system according to the channel environment to enhance the performance of removing interference. The experiment result shows that the ITU 3GPP (3rd Generation Partnership Project) recommended specifications are met on both down-link and up-link. The cancellation was 25dBm, the window size was 500ns/1us, and the max. power was +10dBm. By using algorithms selectively according to the change of environment, the system reduced unnecessary use of hardware resources, and enhanced the convergence rate.
