Abstract:
This work aims to discuss briefly the relevant technical aspects for introduction and expansion of Digital TV retransmission services based on OFDM Multiplexing. The initial channel allocation, proposed for introduction of Digital TV in Brazil, will carry the spectral overload problems of the current analogical systems.The use of single frequency networks (SFN) appears as an efficient solution for channel allocation.
