Writing on Insertion Paper
Source: AT&T Labs
The capacity of insertion channels, even in the presence of feedback, is an open problem in information theory. In this paper, the authors prove that the capacity of insertion channel with non-causal insertion information at the transmitter is 1 even when the receiver do not know the insertion pattern. This paper considers two insertion models, namely random insertion model and the sticky insertion model. For both these models, interference-free capacity of 1 is obtained even when the receiver does not know the interference (insertion pattern).
