A new channel code for decreasing inter-symbol-interference in diffusion based molecular communications

摘要

Molecular communication is a new framework in data communication based on biological mechanisms and systems. In molecular communication system, the transmitter sends information by transmitting certain chemical molecules called data molecules and after propagation of the molecules in the environment they are collected and decoded by the receiver. Due to randomness in the movement of the molecules, they would arrive at the receiver out of order and cause inter-symbol interferences (ISI) problem. Channel coding techniques are commonly used in this situation to tackle the problem. In this paper, we introduce a new family of channel codes, called Crossover Resistant Coding with Time Gap (CRCTG), to reduce the effect of ISI in molecular communications. The performance of the proposed coding schemes are analyzed and compared by simulations with the existing techniques.
