We propose a low-complexity intercarrier interference/intersymbol interference (ICI/ISI) equalizer for multicarrier transmissions over doubly dispersive channels. Decision-feedback (or interference cancellation) is used with respect to both time and frequency. The ICI stage employs an extension of the iterative LSQR algorithm using groupwise interference cancellation with reliability-based sorting...
We propose a frequency-domain method for equalizing intercarrier interference (ICI) and intersymbol interference (ISI) in multicarrier transmissions over rapidly time-varying and strongly delay-spread channels. Postcursor ISI is cancelled by a decision-feedback structure, and ICI is equalized by a sequential version of the recently proposed LSQR equalizer, based on a band approximation for the frequency-domain...
For OFDM transmission over rapidly varying channels, intercarrier interference (ICI) constitutes a major source of performance degradation. We propose a low-complexity ICI equalization technique that uses the iterative LSQR algorithm for regularized inversion of a triple-band approximation to the frequency-domain channel matrix. The LSQR algorithm achieves regularization of the (typically ill-conditioned)...
We consider wireless OFDM communications over rapidly varying channels as occurring e.g. in high-mobility scenarios. Here, intercarrier interference (ICI) is the major source of impairment that limits the transmission quality. In this paper, we propose novel equalizers to combat ICI and enable reliable communications even at high Doppler frequencies. In contrast to existing frequency-domain approaches,...
