Abstract
With the development of wireless communication technologies and the Internet, the application scenarios of positioning technologies are becoming more and more abundant. Therefore, the demand for location-based services is increasing greatly. Moreover, due to the widespread deployment of commercial WIFI devices, a WIFI-based localization system is very promising. This paper focuses on the localization algorithms utilizing Channel State Information (CSI) based on a conventional MUSIC algorithm in a single-node indoor localization system. However, the conventional MUSIC algorithm searches all the peaks in spatial spectrum. It requires enormous computation and thus is unsuitable for accurate positioning applications. This paper is intended to improve the algorithm in terms of positioning accuracy and computational complexity. Numerical results show that the proposed algorithm can improve the positioning accuracy and reduce computational complexity.
