Receiver Design Considerations in Concentration-Encoded Molecular Communication Based on Sampling Rate Selection

Abstract

In this position paper, the roles of sampling rate, i.e. alternatively, sampling time, have been investigated in the receiver design of a concentration-encoded molecular communication (CEMC) system. While several signal detection algorithms so far in CEMC are based on uniform sampling of concentration intensity at the RN, this paper presents four new sampling rate selection schemes based on both uniform and nonuniform sampling rates at the RN, which would potentially be useful in designing computationally-efficient CEMC receiver. This paper has mainly focused on reducing the total number of samples that the RN needs to sense and/or process in order to reduce the computational burden of the receiver.
