Molecular communications systems use the presence or absence of a selected type of molecule to digitally encode messages. The molecules are delivered into communications media such as air and water for transmission. The technique also is not subject to the requirement of using antennas that are sized to a specific ratio of the wavelength of the signal. Molecular communication signals can be made biocompatible and require very little energy.
A method and device for adapting a molecular communication channel based on transfer learning
ActiveCN121603134BMolecular communicationTraining Transfer
The application discloses a kind of based on transfer learning's molecular communication channel adaptation method and device, method includes: using diffusion-advection-reaction equation as channel impulse response model, and constructs molecular communication system simulator;Collect original channel body temperature, target channel body temperature, and obtain original channel environment and target channel environment based on channel environment calculation model;Simulate original channel sequence and target channel sequence, obtain original channel dataset and target channel dataset;Domain alignment transfer learning model based on hybrid neural network is constructed, and based on original channel dataset, target channel dataset training transfer learning model, obtain the molecular communication symbol detection model of adaptation target channel, and carry out molecular communication under target channel based on molecular communication symbol detection model.The application is applied to molecular communication field, and channel adaptation of molecular communication can be quickly realized, which provides an effective way for solving symbol detection problem in resource-limited scene.
