APPARATUS AND METHOD FOR EFFICIENT TRANSMISSION BROADCASTING CHANNEL UTILIZING CYCLIC DELAY DIVERSITY

摘要

Disclosed are an apparatus and a method for efficiently transmitting a broadcasting channel by means of cyclic delay diversity in an OFDM mobile communication system. The method comprises the steps of setting each transmitter to have different delay values, the transmitter providing a service to adjacent service areas, generating OFDM signals including the broadcasting data by said each transmitter, delaying the OFDM signals by means of the different delay values, and transmitting the delayed OFDM signals by means of each transmitting apparatus.
