Molecular communication method and receiver for molecular communication

Abstract

The invention provides a molecular communication method and a receiver for molecular communication. The method is executed at a receiving end. The method comprises the following steps: respectively detecting a first concentration of messenger molecules which are sent from a transmitting end through a biochemical environment and carry original bit information, a second concentration of reactant molecules existing in the biochemical environment, and a third concentration of product molecules generated by reaction of the messenger molecules and the reactant molecules in the biochemical environment in a bit time slot, obtaining a first concentration curve, a second concentration curve and a third concentration curve; respectively carrying out concavity and convexity measurement on the first concentration curve, the second concentration curve and the third concentration curve to obtain a first measurement index, a second measurement index and a third measurement index; respectively comparing the first measurement index, the second measurement index and the third measurement index with a preset adaptive threshold to obtain a first detection result, a second detection result and a third detection result of the original bit; and performing comprehensive judgment based on each detection result to obtain a recovery bit of the original bit.

Description

technical field [0001] The present disclosure relates to the technical field of molecular communication, in particular to a molecular communication method and a receiver for molecular communication. Background technique [0002] In recent years, nanotechnology, synthetic biology and other fields have continued to develop, providing a certain hardware foundation for molecular communication-related research. The overall facilities and methods of molecular communication have good biocompatibility. After the nano-network based on molecular communication is implanted into the human body, it can sense the surrounding environment, tissues and organs more accurately, and give timely warning when a lesion is detected. , so the realization of reliable molecular communication is conducive to the further development of biomedicine. Molecular communication uses the molecule itself as the information carrier, and uses the concentration, type, and release time of the messenger molecule as...

Problems solved by technology

However, coherent detection technology must accurately obtain channel state information and complex digital signal processing, which is not only cumbersome, but also the detection effect of coherent detection is also affected by the transmission rate of the channel, resulting in a high bit error rate in the molecular communication process
