摘要：
This paper presents a design of a systolic array of an adaptive filter. The filter is based on the least mean square (LMS) algorithm, but due to the problems in implementation of the systolic array, a modified algorithm, a special case of the delayed LMS (DLMS), is used. The DLMS algorithm introduces a delay in the updating of the filter coefficients. The convergence and steady state behavior of the systolic array are analyzed. It is shown that the performance of the systolic array is similar to that of a conventional LMS implementation in a wide range of practical conditions.
