Abstract

An inter-channel interference (ICI) cancellation method and apparatus for OFDM based systems. The method includes configuring one or more redundant sub-carriers to reduce or cancel intra-band and inter-band ICI experienced by the target sub-carriers. The number and positions of the redundant sub-carriers are highly flexible.
