This thesis chiefly is studying on the foundation of adaptive filter theory, and analyzed component principle and the numeral realization of the adaptive filter foundation, and has carried on the numeral optimum design to the adaptive filter. And still using MATLAB's simulation tool, the adaptive filter has been in progress analyzing many times to what this real application was offset by the noise, and reached the numeral realization theory basis that optimizes.
The design analysis of LMS's algorithm designing under DSP's chip for a special purpose, and combines the most advanced DSP of present time to realize that the technology is accomplished the high performance of this algorithm and is realized.
