Abstract
Although LMS adaptive filters have been applied to many signal processing applications, there exists a critical limitation of the conventional adaptive filter when it is applied for a real time signal processing. It is simply because of its required lengthy convolution (filtering) calculation. To overcome the limitation, we propose a new Delayed LMS algorithm which is implemented in Signed-Digit Number system. In the paper, a new pipelined adaptive filter is developed and its detailed analysis is described with an actual VLSI implementation.
