Abstract

The invention, which belongs to the technical field of identification, relates to a deep learning identity recognition system and method based on channel state information of a wireless network. The deep learning identity recognition system is composed of a wireless signal transmitter, a wireless signal receiver, a control terminal and a cloud server. The wireless signal receiver and the wirelesssignal transmitter are equipped with wireless network cards and are arranged in a room at an interval. The wireless signal transmitter is used for sending a wireless signal with CSI information; the wireless signal receiver is used for acquiring wireless network channel state information in an environment and uploading the information to the cloud server. According to the system provided by the invention, the blank of passive identity identification application is filled; and an application example is built for deep-learning-based passive recognition and positioning. The system can be appliedto fields of personnel attendance, smart home intrusion detection, patient monitoring and the like widely.

Description

technical field [0001] The invention belongs to the technical field of identification, and relates to a deep learning identification system and method based on wireless network channel state information. This system is a sampling identification of a CSI (Channel State Information) signal using a common WiFi signal. Cooperate with the unique deep machine learning algorithm to carry out model recognition training on the CSI signal of WiFi, thus realizing the recognition system of human body identification. Background technique [0002] In application scenarios such as health monitoring, security detection, and smart home, identification plays a very important role. Existing active identity recognition systems generally use technologies such as fingerprint recognition and iris recognition. Although they can realize recognition and authentication functions, the user under test needs to make specified actions, and there are problems such as expensive equipment and limited recogni...
