- W2045754611 abstract "In this paper, we analyze the effect of Carrier Frequency Offset (CFO) of multiple users on the SINR of a single user in OFDMA based uplink communication receiver. We have computed an explicit SINR expression for two types of mapping strategies used in uplink OFDMA systems namely Interleaved Frequency Division Multiple Access (IFDMA) and Localized Frequency Division Multiple Access (LFDMA). SINR expressions in case of carrier frequency offset correction are also computed. Using simulations, we have compared the total average interference due to different values of CFO's of multiple users for both mapping schemes. Simulation results also show that the average value of Inter-Carrier Interference (ICI) for localized mapping is higher than interleaved mapping while the average value of Multiuser Interference (MUI) is higher for interleaved mapping. Moreover, the average MUI for localized mapping is minimum at the center of the band and it increases as we move towards the band edges. We also observe a flat response for ICI and MUI for interleaved mapping." @default.
