Abstract :
Digital audio broadcasting offers the potential to give every radio in Europe the sound quality of a compact disc. To accomplish this, it requires a rugged method of transmission. The coded orthogonal frequency division multiplexing (COFDM) modulation system was developed to meet this need. The paper describes the reasons why a new modulation process was needed, and explains how the COFDM system has been optimised to meet the requirements
