Abstract

The LMS algorithm (Least mean square) is common in the adaptive algorithm system. It has a simple calculation and convenient implementation. The convergence performance is excellent and the stability is high in the case of limited precision. The advantages of anti-interference on filtering are obvious. In this paper, the concept of LMS algorithm, the working principle and the selection of technical research scheme on frequency estimation are introduced, and we realize the LMS algorithm by FPGA technology and used it in clutter rejection area.
