Towards Anti-interference Human Activity Recognition Based on WiFi Subcarrier Correlation Selection

As an essential technology in the field of the Internet of Things, Human activity recognition (HAR) is a well-researched topic. Recently, some state-of-the-art WiFi-based HAR systems have been presented due to its characteristics of no-invasion, no privacy leakage, and high recognition accuracy rates (RARs). However, the commodity WiFi devices for identification are usually in a complex electromag...
