Molecular communication encoding method and apparatus, and relay nano machine

Abstract

The present invention discloses a molecular communication coding method and apparatus, and a relay nano machine. The method includes the following steps: receiving quaternary encoded transmission information sent by a transmit end; and parsing the quaternary encoded transmission information according to a preset decoding rule to obtain decoding information; sending the decoding information to a receive end according to a preset transmission rule, so that the receive end decodes the decoding information according to the preset decoding rule. The method combines characteristics that intensity ofinter-symbol interference is affected by the number of transmitting molecules of a sender nano machine in a process of molecular communication, so that the inter-symbol interference and the number ofmolecules used in molecular communication are reduced, and detection difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of molecular communication, in particular to a molecular communication encoding method, device and relay nanomachine. Background technique [0002] The rapid development of biotechnology and nanotechnology has paved the way for the fabrication of nanomachines. Nanomachines are considered to be the most basic functional devices at the nanoscale. Nanomachines have promising application prospects in medicine and industry. However, the application of nanomachines in these fields is easily constrained by the characteristics of nanomachines, such as the small size and unknown physical properties of nanomachines, which lead to the uncontrollability and instability of nanomachines in applications. These problems can be solved by the coordination of nanoscale communication between nanomachines, resulting in the formation of networks among nanomachines called nanonetworks. Nano-networks can coordinate different nan...

Problems solved by technology

This molecular communication demodulation algorithm based on the number of molecules is very simple to implement, but due to the random diffusion characteristics of molecules and the intersymbol interference caused by the accumulation of residual molecules in the medium is very serious, the bit error rate of signal discrimination is high, The reliability of the molecular communication process has been greatly affected

At the same time, because the number of molecules is inversely proportional to the square of the transmission distance, as the transmission distance increases, the number of molecules attenuates seriously, making the detection more difficult
