Performance Analysis of D-MoSK Modulation in Mobile Diffusive-Drift Molecular Communication Relay System

Molecular communication is a kind of communication method that uses tiny particles to encode, transmit and receive information. It has the characteristics of good biocompatibility and small size. With the increase of molecular diffusion distance, the signal attenuation is serious. In order to solve above question, a mobile diffusive-drift MC relay model is built, in which wu use the depleted molecule shift keying (D-MoSK) modulation, and use the maximum likelihood detection to detect signal. We derive he closed form expression of symbol error rate (SER) and the channel capacity. The simulation results show that different parameters have an important impact on the system performance.
