2-D PIPELINED ADAPTIVE FILTERS BASED ON 2-D DELAYED LMS-ALGORITHM

A pipelined adaptive digital filter (ADF) architecture based on a two- dimensional least mean square algorithm is proposed. This architecture enables the ADF to be operated at a high crock rate and reduction of the required amount of hardware. To achieve this reduction we introduc e a new building unit, called a brock, and propose implementing the pi pelined ADF using the block. Since the number of blocks in a cell is a djustable, we derive a condition for satisfying given specifications. We show the smallest number of blocks and the corresponding delay can be determined by using the proposed method.
