Sammanfattning

We consider the problem of lower bounding the information rate of intersymbol interference channels via Monte Carlo algorithms.
We adopt a novel approach based on the Ungerboeck observation model, unlike the existing ones that are all based on the Forney model.
The two approaches, yet equivalent in the case of full-complexity detection, lead to different results in the case of reduced-complexity detection, which is the only viable option when the channel memory is large.
In particular, the proposed approach significantly outperforms the existing ones at low-to-medium values of the signal-to-noise ratio.
