MOL-Eye: A New Metric for the Performance Evaluation of a Molecular Signal
Inspired by the eye diagram in classical radio frequency (RF) based
communications, the MOL-Eye diagram is proposed for the performance evaluation
of a molecular signal within the context of molecular communication. Utilizing
various features of this diagram, three new metrics for the performance
evaluation of a molecular signal, namely the maximum eye height, standard
deviation of received molecules, and counting SNR (CSNR) are introduced. The
applicability of these performance metrics in this domain is verified by
comparing the performance of binary concentration shift keying (BCSK) and BCSK
with consecutive power adjustment (BCSK-CPA) modulation techniques in a
vessel-like environment with laminar flow. The results show that, in addition
to classical performance metrics such as bit-error rate and channel capacity,
these performance metrics can also be used to show the advantage of an
efficient modulation technique over a simpler one
