Title
Doppler compensation for OFDM transmission by sectorised antenna reception
Abstract
Rapidly time-varying channels are a major obstacle for successful data transmission via OFDM. The resulting loss of orthogonality among neighbouring subcarriers leads to intercarrier interference (ICI). Hence, coherent receivers suffer from the impediment of both channel estimation (CE) and subsequent data detection, whereas noncoherent receivers are suffering from reduced correlation between adjacent symbols. Literature contains numerous approaches to cope with this problem working either in time or frequency domain. Our concern in this paper is a novel time-domain method which relies on the use of multiple directional receive antennas. Each of these antennas experiences only a fraction of the total Doppler spread of a comparable omnidirectional antenna. We will demonstrate that our scheme copes well with large maximum Doppler frequencies. Copyright (C) 2008 John Wiley & Sons, Ltd.
