Lms algorithm FOR NON-STATIONARY INPUTS FOR THE PIPELINED IMPLEMENTATION   
OF ADAPTIVE ANTENNAS

Arjun Arunachalam


ABSTRACT

In this project, a modified LMS algorithm has been proposed which is capable 
of handling non-stationary inputs. The algorithm is then modified for the 
pipelined implementation of adaptive antennas which have higher throughput 
.A number of recently proposed Approximation techniques when applied to 
standard LMS algorithm can result in instability due to a change in the 
functionality of the algorithm and thus careful calibration of step size and 
depth of pipelining is needed. This project also studies the   issues 
involved with the various approximations techniques used to reduce the 
overhead involved when the look-ahead technique is applied to a standard LMS 
algorithm. I obtained the inspiration for this in the course of my study in 
the field of Adaptive filters .The hardware implementation issues involved 
with adaptive filters are subtle yet challenging.
