Problems solved by technology

[0005] At present, there are mainly three methods of human body channel modeling as follows. The first one is to establish the model by considering the whole human body as the same homogeneous medium. This modeling method is relatively simple. However, since the human body itself is not a uniform medium, it causes There will be a large gap between the channel characteristics calculated by this model and the actual value; the second modeling method is to voxelize the human body, which is very complicated and requires a very large computer memory space during calculation , the

Abstract

The invention discloses a human body communication channel modeling method and system. The method comprises the following steps: dividing a human body into a skin layer, a fat layer, a muscle layer and a skeleton layer from the whole; establishing models of the skin layer, the fat layer, the muscle layer and the skeleton layer; and combining the skin layer model, the fat layer model, the muscle layer model and the skeleton layer model to form a complete human body model. The human body communication channel modeling method provided by the embodiments of the invention is not only short in simulation time, but also is higher in simulation accuracy.

Description

technical field [0001] The invention relates to the technical field of human body communication, in particular to a method and system for modeling a human body communication channel. Background technique [0002] Human body communication technology is a communication technology that uses the human body as the signal transmission medium. Its basic idea is to load communication signals on the surface of the human skin and transmit them in the human body. At the receiving end, the high-sensitivity receiver detects the weak electrical signal transmitted through the human body, thereby realizing data communication using the human body as the medium. Compared with the existing short-distance wireless communication technologies such as Bluetooth, the human body communication technology has the advantages of high-quality signal transmission, high transmission rate, high security, contact network access, and no communication bandwidth problem. Personal area network, computer network...
