inter-User Equipment（UE）interference and innate frequency offset at the receiver/transmitter sides

this paper proposes a novel method suitable for the frequency offset estimation at multi-UE base station side of LTE systems.It first estimates the size of frequency domain broadening generated by window function.Then it analyzes the size and scope of the frequency offset interferences brought about by band-adjacent UE and designs to eliminate these interferences.Finally

it estimates the frequency offset by utilizing the relationship between the frequency offset and the cross-correlation function.The link simulation results show that this method reduces the inter-UE interferences and overcome the influences resulted from multipath effects and inaccurate timing to a great extent

achieving superior frequency offset estimation fitting and block error rate performance to those in various conventional methods.
