Abstract
In mobile wireless communication systems the channel between the transmitter and receiver varies during a transmission. This is often referred to as fading, of which different kinds exist—each resulting in different impairments with specific properties. A low complexity scheme is described to reduce the noise created by inter-carrier interference or ICI. The method makes use of the guard interval and assumes slow variation of the channel. It is not restricted to wireless communication and can be used in any environment with varying channels.
