This work in progress investigates the achievable rate of a diffusive Molecular Communication (MC) channel with a fully absorbing receiver, which counts particles absorbed along each symbol interval and resets the counter at every interval (reset-counting). We optimize the detector threshold for maximizing capacity, approximate as Gaussian the received signal distribution, and calculate the channel mutual information affected by ISI, in the case of BCSK modulation. The results demonstrate that when the symbol interval is small (strong ISI), the maximum achievable rate does not occur with equiprobable transmission of bits.

Abstract
This work in progress investigates the achievable rate of a diffusive Molecular Communication (MC) channel with a fully absorbing receiver, which counts particles absorbed along each symbol interval and resets the counter at every interval (reset-counting). We optimize the detector threshold for maximizing capacity, approximate as Gaussian the received signal distribution, and calculate the channel mutual information affected by ISI, in the case of BCSK modulation. The results demonstrate that when the symbol interval is small (strong ISI), the maximum achievable rate does not occur with equiprobable transmission of bits.File in questo prodotto:
