Adaptive Rate-Maximizing Channel-Shortening for ISI Channels

Summary, in English

We consider detection over intersymbol interference channels that are unknown at the receiver. For such a kind of systems, we consider an alternative approach to the design of a reduced-complexity receiver based on channel shortening without the explicit estimation of the channel impulse response. The proposed solution allows a simplification of the receiver architecture and a faster convergence for channels with a long memory and a few number of poles.
