Abstract
In this paper, the expressions of achievable strength-based suboptimum detection probabilities of concentration-encoded molecular communication (CEMC) system have been derived based on pulse-amplitude modulated (PAM) on-off keying (OOK) modulation scheme. Results show that the detection performance of a PAM OOK CEMC system significantly depends on the statistical parameters of diffusion noise and intersymbol interference (ISI). Analytical performances of ISI-free and ISI-affected scenarios have been explained and compared based on receiver operating characteristics (ROC) curves for impulse (i.e. spike)-modulated (IM) and PAM schemes. It is shown that the effects of diffusion noise and ISI on ROC can be explained separately based on their communication range-dependent statistics.
