Abstract:
In multi-carrier systems, distributed resource allocation of the resources of multiple user equipments (UEs) can result in better frequency diversity gain but can also induce Inter-Carrier Interference (ICI) between UEs. This ICI can become quite serious in a high mobility environment. Based on a novel radio channel model for ICI cancellation in multi-carrier systems and an iterative channel estimation scheme for ICI cancellation in multi-carrier systems, the present invention provides a simplified equalization scheme in the frequency domain to determine and remove ICI of both a targeting UE as well as other UEs.
