Abstract :
The repeater is a bi-directional duplex amplifier working between base station and mobile station. Based on adaptive interference cancellation technology, the scheme and algorithm of adaptive interference cancellation are studied in this paper. The comprehensive structure of adaptive interference cancellation is implemented on FPGA. The simulation and test results show that the interference problem of the traditional repeater is effectively solved by using the adaptive interference cancellation device.
