Very noisy channels (VNCs) are discrete memory less channels whose capacity is very small (almost zero). Many real life channels specially functioning at low S/N ratios have properties identical to very noisy channels (VNCs). In the present work, we have established some new results on channel capacity of VNCs which may be useful in building mathematical models for such channels and in the other contexts...
A number of modern storage technologies, when written to, exhibit substantial variability in the outcome of a write action. It is possible to mitigate the effect of the write uncertainty through the use of a feedback loop that rewrites the memory whenever judged necessary, in effect reshaping the write noise. This scheme highlights a tradeoff between the storage capacity of the memory and the cost...
