The delay selector channel: Definition and capacity bounds

Abstract

A new timing channel, known as the delay selector channel (DSC), is proposed as an abstract model for applications with timing noise. In this model, channel inputs are delayed by a random amount, and delayed transmissions are summed at the output. Molecular communication is discussed as a principal application of the DSC, since the channel mimics the propagation and reception of molecules under Brownian motion. In this paper, the DSC is described in detail, and a closed-form lower bound is given on capacity.
