DSFN: Dynamic Single Frequency Network
Dynamic Single Frequency Networks (DSFN) is a transmitter macrodiversity technique for, for example, OFDM-based cellular networks. DSFN is based on the idea of single frequency networks (SFN), which is a group of radio transmitters that send the same signal simultaneously over the same frequency. The concept of DSFN implies that the SFN grouping is changed dynamically over time, from timeslot to timeslot. 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.
