Comparison of amplitude detection techniques for passive receivers in molecular communications

Abstract

Amplitude detection is based on observations of the information carrying molecules made at the receiver and can be enhanced by optimizing the timing and the number of them. In this paper, a diffusion-based molecular communications system with a passive receiver is analysed under two different amplitude based detection techniques. In particular, low complexity detectors utilizing a single or multiple observations are evaluated and compared in terms of the achievable mean error probability, when external noise and interference are considered.
