FPGA implementation of adaptive interference canceler for periodic signal.

摘要

This thesis describes the design, implementation and testing of an adaptive digital interference canceler for periodic signals. This canceler uses the least mean-square (LMS) adaptive filtering technique to eliminate interference from an input signal. An advantage of the adaptive interference cancelling approach is that it requires no prior knowledge of both the signal and the interference characteristics. A digital design approach is used in this thesis because of its reliability and accuracy. The canceler implemented using a Xilinx FPGA chip. A prototype design demonstrated that the canceler was able to reduce the input interference power by about 40%.Dept. of Electrical and Computer Engineering.
