Interference modeling and analysis in two-hop cellular network with fixed relays in FDD mode
Li Ping, Mengtian Rong, Tao Liu, Yu Dai · 2005
Relaying network is expected to play an important role in the future wireless network. This paper presents a scheme of two-hop cellular network with fixed relay nodes (FRN). Based on this scheme, co-channel interference and SIR received by BS and FRN are analyzed. Both the theoretical analysis and simulation results show that the SIR can be improved significantly when relays are employed in the network. We also show that the antenna height of FRN and the cell radius of BS and FRN influence SIR received by BS and FRN greatly.
