Convolutional neural networks based indoor Wi-Fi localization with a novel kind of CSI images

Indoor Wi-Fi localization of mobile devices plays a more and more important role along with the rapid growth of location-based services and Wi-Fi mobile devices. In this paper, a new method of constructing the channel state information (CSI) image is proposed to improve the localization accuracy. Compared with previous methods of constructing the CSI image, the new kind of CSI image proposed is able to contain more channel information such as...
