| 摘 要： | IntroductionRelaying is well known for its potential of ex-tending the high data rate coverage of a single basestation and reducing infrastructure deploymentcosts. Moreover, it is efficient in solving the cov-erage problem behind the obstacles and eliminatingblack spots, which even can not be solved by intro-ducing smart antenna technology1,2]. Some dumbrelays (analog repeaters) have been adopted1]in2 G and 3 G systems. But in such scenarios, thesignals received are forwarded without any si…

| Abstract: | This paper presented a scheme 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. |
