Abstract :
This paper presents a new finite filter synthesis algorithm which promises higher transmission power in digital radios based on improving the conventional Remez algorithm. Such degradations as caused by Gaussian thermal and rather frequency selective fading are effectively recovered through improving the nullity of the transmission filters
