Residual ISI cancellation for OFDM with applications to HDTV broadcasting.

Residual ISI cancellation for OFDM with applications to HDTV broadcasting.

An iterative technique is developed for orthogonal frequency division multiplexing (OFDM) systems to mitigate the residual intersymbol interference (ISI) that exceeds the length of the guard interval. The technique, called residual ISI cancellation (RISIC), uses a combination of tail cancellation an...
