IEC 62002-1:2008 is a radio access specification for mobile, portable and hand-held portable devices capable of receiving DVB-T/H services. It includes informative system aspects as well as specifications for minimum RF-performance. It covers terminals in three main classes, namely integrated car terminals, portable digital TV sets and hand-held portable convergence terminals. Interoperability with integrated cellular radios is also considered. This second edition cancels and replaces the first edition, published in 2005 and constitutes a technical revision. The main changes with respect to the previous edition are: - DVB-H has been included as a part of the main specification; - All the performance figures have bee revised as new simulation results have been made available as well as new reference receivers for DVB-H have been developed; - DVB-H now includes all the different MPE-FEC code rates; - New portable indoor and portable outdoor channel models have been included as well as performance figures for those; - A new 2x TU-6 mobile SFN test channel has been included; - A new L4 linearity pattern has been added; - Dedicated performance figures for DVB-H for S1, S2, L1 to L4 interference patterns have been included; - A new GSM-interference measurement method has been added. The contents of the corrigendum of July 2008 have been included in this copy. The content of the corrigendum 1 (2008-07) has been included in this copy. LIEC 62002-1:2008 est une specification dacces radio pour les dispositifs mobiles, portables et portatifs capables de recevoir des services DVB-T/H. Elle inclut des aspects informatifs relatifs au systeme, ainsi que des specifications relatives aux performances RF minimales. Elle couvre les terminaux de trois categories principales, a savoir les terminaux integres aux vehicules automobiles, les televiseurs numeriques portables et les terminaux convergents portatifs. Linteroperabilite avec les radios cellulaires integrees est egalement prise en consideration. La specification couvre les domaines suivants. - Plages de frequences - Modes pris en charge - Definition des conditions de reception - Definition du modele de reference RF du recepteur - Definition des criteres de degradation - Caracteristiques de lantenne - Modeles de canaux - Performances C/N avec differents canaux - Niveaux dentree minimal et maximal - Immunite aux signaux brouilleurs - Definition dun ensemble de types dinterferences - Tolerance au brouillage impulsif - Performances SFN - Performances minimales de lemetteur - Interoperabilite des radios cellulaires - Aspects CEM LIEC 62002-1:2008 annule et remplace la premiere edition parue en 2005. Elle constitue une revision technique. Les principales modifications par rapport a ledition precedente sont indiquees ci-dessous. Le DVB-H a ete integre dans la specification principale. Tous les chiffres relatifs aux performances ont ete revises pour tenir compte des nouveaux resultats de simulation et du developpement de nouveaux recepteurs de reference DVB-H. Le DVB-H inclut a present lensemble des differents debits de code MPE-FEC. De nouveaux types de canaux de propagation "portable en interieur" et "portable en exterieur" ont ete ajoutes ainsi que les performances chiffrees avec ces canaux. Un nouveau canal dessai SFN mobile 2x TU-6 a ete inclus. Un nouveau type de linearite L4 a ete ajoute. De nouveaux chiffres qui decrivent les performances particulieres du DVB-H pour les types dinterferences S1, S2, L1 a L4 ont ete integres. Une nouvelle methode de mesure des interferences GSM a ete ajoutee. Le contenu du corrigendum 1 (2008-07) a ete pris en consideration dans cet exemplaire.
