Noise Modeling Of Nanomechanical Communication Systems

In a recent paper 121, we introduced a framework for performing nanomechanical communication, where nanomechanical systems can communicate using mechanical movements to encode and transfer information between a transmitter (TX) and a receiver (RX). The framework considered in 121 was mainly focused on the deterministic model, which is the noise-free case. It was shown that the encoding of movements or motions is key to the transfer of information. In this paper, we address how noise affects such a communication system. We introduce two modes of NMC: synchronous versus asynchronous. We show that synchronous mode can achieve higher transmission rates compared to asynchronous mode. As an example, the symbol error rate expression for a transmitter-receiver pair with 4 degrees of motion is given by analyzing the different motion state transitions.
