摘要：
An ICI cancellation iterative receiver and an ICI cancellation method in the wireless communication system is provided. In order to eliminate the Inter-carrier-interference (ICI) due to phase noise, an adaptive ICI cancellation scheme based on the wireless communication system is presented. In order to correct the contaminated preamble symbols due to phase noise, a first LMS adaptive filter in the receiver cancels the ICI. In the following data symbols of a frame, joint of the turbo decoder and channel estimation is provided. The complexity of the joint algorithm is analyzed and the algorithm can be implemented in the wireless communication system. The simulation results show that the performance can be improved dramatically.
