[1] Digital wireless communication systems based on the OFDM modulation scheme are well-suited to SFN operation, since OFDM in combination with some forward error correction scheme can eliminate intersymbol interference and fading caused by multipath propagation without the use of complex equalization.
[1] The aim is to achieve efficient spectrum utilization for downlink unicast or multicast communication services in centrally controlled cellular systems based on for example the OFDM modulation scheme.
A centralized scheduling algorithm assigns each data packet to a certain timeslot, frequency channel and group of base station transmitters.
DSFN can be considered as a combination of packet scheduling, macro-diversity and dynamic channel allocation (DCA).
DSFN makes it possible to increase the received signal strength to a mobile terminal in between several base station transmitters in comparison to non-macrodiversity communication schemes.
