  2. 1. Single frequency broadcasting networks

    Author : Göran Malmgren; KTH; []
    Keywords : ;

    Abstract : An Orthogonal Frequency Division Multiplexing (OFDM) schemeallows all transmitters in a radio network to transmitidentical signals in the same frequency block, forming a socalled Single Frequency Network (SFN). By avoiding frequencyreuse, substantial improvements in bandwidth utilisation arepossible. READ MORE
