Abstract
One promising technique for communicating at the nanoscale is molecular communication (MC). In a molecular-communication-via-diffusion-scenario, the memory component of the channel is very high. This gives rise to what is known as inter-symbol interference. Traditional channel coding schemes cannot be utilized in MC due to the high memory. In this paper, a novel low complexity channel coding method is proposed for the molecular communication domain. The design of the proposed channel code takes into account the capability of a nano-device and the characteristics of the molecular communication channel. Simulation results confirm that the proposed method provides a significant improvement in terms of bit error rate. Moreover, a proof-of-concept implementation of the proposed coding scheme is done on a macro-scale testbed. The reliability of the communication link is shown to be significantly increased.
