Reachability of the capacity in parallel quantised channels

Based upon profound knowledge about wireless communication systems that was gathered during the past decades, modelling biological systems analogously has become more and more popular. Although the assumptions about the latter are sometimes less reliable than those about technical systems, some models have proven useful in explaining the behaviour of biological communication systems for example when affected by diseases like Alzheimer. In this work, such a model based upon parallel quantised channels is examined further. The key aspect is to figure out whether the proven capacity bounds are reachable, and under which conditions.
