| 摘 要： | This paper presented ascheme of two-hop cellular network with fixed relay nodes （FRN）. Based on this scheme, co-channel interference and signal interference ratio（SIR） received by base station（BS） and FRN were analyzed. Both the theoretical analysis and simulation results show that the SIR can be improved significantly when relays are employed in the network. The higher spectral efficiency can be obtained due to the improved two-hop link quality through the use of adaptive modulation and coding （AMC）. The antenna height of FRN and the cell radius of BS and that of FRN influence SIR received by BS and FRN and the system spectral efficiency greatly. The proper antenna height of FRN and cell radius of BS and that of FRN were also given to get the highest spectral efficiency.
