QoSControl ofDRIVISystem Based on Artificial Neural Network

Digital RadioMondiale (DRM)isanewdigital radiobroadcasting system forthefrequency bandsbelow30 MHz. A highquality ofaudioanddatatransmission is achieved byadoption oftheCOFDM modulation witha multilevel coding scheme, whichhashighresistance tothe multipath fading andinterference. Itadaptstobeimple- mentedinsingle frequency network(SFN):a transmitter networkinwhichalltransmitters broadcast identical infor- mationsimultaneously atthesamefrequency. Thenetwork quality ofservice (QoS)control strategy isspecified inthis paper, anda newnetworkQoScontrol methodbasedon artificial neural network isdiscussed.
