Summary:
In this paper, it is proposed the information delivery system that the transmission signal embraces together the wide-area information and the local area information. The distant user from the base station receives the wide-area information only and the nearby user receives together the widearea information and the local-area information. The proposed system uses the code shift keying(CSK) for transmitting the local-area information and the amplitude shift keying( ASK) for the wide-area information. In the proposed system, the broadcast information is hierarchized by combining ASK with CSK.
