Receiver design for pulse position modulation technique in diffusion-based molecular communication

Molecular Communication via Diffusion (MCvD) is one of the most prominent approaches to interconnect the nanomachines which can do some simple communication functions. In this paper, Pulse Position Modulation is studied. We proposed two techniques in order to design the receiver for this modulation. These detection methods called ML and MAX detector. The performances of the proposed detection algorithms are discussed in the different ISI values. It is seen that two detection methods can achieve the same performance in bit error probability for some practical cases. While the MAX detector is simpler than ML detector.
