Abstract:
Firstly, this paper gives the concept of radiant power to adjacent channel, then derives the original funct ion of 10 order Bessel analog filter, transformates it to digital filter by Euler approx imat ion for t ransformat ion of an analog f ilter to a dig ital filter, processes separately 2 level and 4 level paging coded signals by the aid of computer, gives the w ay of design for hardware and the flow chart of program. This method can ef ficiently low er the radiant pow er to adjacent channel and reduce adjacent channel interferences, w hen applied to pract ical system
