In this paper, the FPGA (Field Programmable Gate Array) implementation of self interference cancellation technique based on an adaptive LMS (Least Mean Square) algorithm is presented. By using the FPGA Virtex@6 HW module, the field data measured through a RF repeater is adopted to improve a signal quality and to reduce oscillation of the system due to the feedback interference signal coming from transmit antenna of a WCDMA radio repeater. As a result, the proposed module, which was simulated by Xilinx System Generator, a high efficiency and achievs the a similar performance in comparison with the implementation result. Because of FPGA implementation, the designed technique offers more flexibility than existing methods.
