Design and implementation of LMS adaptive filter algorithm based on FPGA

摘要

In the occasion of real-time requirements and harsh electromagnetic environments, currently adaptive filtering algorithm is most based on the DSP chip, using of Assembly Language and high-level language programming procedures, and the speed of processing and the performance of noise immunity are not match the requirement. LMS adaptive filter is a widely used digital signal processing algorithms. Due to the high flexibility and the high integrated of FPGA technology, this paper propose a LMS algorithm using FPGA technology to achieve it, and well used in adaptive filter, not only meet the needs of flexibility and real-time for systems, but also easy to implement, compared with other algorithms it is more simple and more reliable. It has good prospects in the field of signal processing.
