Abstract

The invention relates to a human body communication channel modeling method based on a non-uniform medium and a system thereof. The method comprises the following steps that a human body is divided into multiple structural models according to the structure; the multiple structural models are abstracted into regular geometries; medium layer division is performed in the internal parts of all the structural models, thickness of all medium layers is arranged, and equivalent electrical parameters of all the structural models are computed; and the uniform medium structural models with different electrical parameters are recombined and a human body contour is recovered so that multiple non-uniform medium human body electromagnetic models of the uniform medium structural models with different electrical parameters are constructed. According to the aforementioned human body communication channel modeling method based on the non-uniform medium and the system thereof, the non-uniform medium human body electromagnetic models of the uniform medium structural models with different electrical parameters are constructed so that accuracy is high in comparison with unified uniform medium human body models. Besides, all the structural models are equivalent to the uniform medium structural models so that subsequent computation is simplified and computation space is saved.

Description

technical field

[0001] The invention relates to the field of human body communication, in particular to a method and system for modeling a human body communication channel based on a heterogeneous medium. Background technique

[0002] Human body communication is a communication method that uses the human body as the transmission medium for signal transmission. In order to study based on numerical calculation and simulation, researchers have adopted the assumption that the human body is a homogeneous medium to simplify the model. However, the human body is a complex heterogeneous medium body, and the homogeneous medium human body model does not conform to the actual situation. The calculated channel characteristics The difference from the actual value is large, and the accuracy of the electromagnetic model of the human body is poor. Contents of the invention

[0003] Based on this, it is necessary to provide a method and system for modeling human body communication channel...
