A new system of sound broadcasting to mobile receivers

The broadcasting channel towards mobile receivers, especiallv in a dense urban area, is particularly hostile,which makes th'e transmission of high bit rate very challenging.The conjunction of an Orthogonal Frequency Division Multiplexing (OFDM technique and a convolutional coding scheme (associated to a Viterbi decoding al orithm) is ,a promising solution (COFDM) studied at CCkTT, that is suitable to cope with such a channel.In the first part of the pa er, the theoretical principles of the system are detailed. f he second part concerns the realization of a com lete COFDM s stem, designed within the framework of tt?e DAB (Digitay Audio Broadcasting) EUREKA 147 project, which is able to broadcast 5.6 Mbit/s in a bandwidth of 7 MHz. For the time being, this rate corresponds to 16 high quality stereophonic programs. network aspects are pointed out as far as the Fz%ction of a new radio broadcasting service is concerned.
