ABSTRACT
Traditional broadcasting systems assign different frequency bands to each transmitter, within a given region in order to prevent interference between transmitters. Frequencies used in a cell will not be allocated in adjacent cells. As an alternative, SFN broadcasting systems [39], where several transmitters transmit the same signal simultaneously and over the same bands, can be employed. Since the distance between a given receiver and each transmitter can be substantially different, the overall channel impulse response can be very long, spanning over hundreds or even thousands of symbols in the case of broadband broadcasting systems; this can cause severe time-distortion effects within this type of single frequency system.
