Abstract :
Narrow band interference suppression in direct sequence signals is a classic communication problem that has received much attention and numerous solutions have been proposed. The paper proposes the use of a non-linear transform domain modified median filter that offers several advantages over the other techniques. Detailed simulation has been carried out and some graphic results are shown.<>
