"Joint Channel Estimation and Signal Recovery for RIS-Empowered Multi-U" by Li Wei, Chongwen Huang et al.

Reconfigurable intelligent surfaces (RISs) have been recently considered as a promising candidate for energy-efficient solutions in future wireless networks. Their dynamic and low-power configuration enables coverage extension, massive connectivity, and low-latency communications. Due to a large number of unknown variables referring to the RIS unit elements and the transmitted signals, channel estimation and signal recovery in RIS-based systems are the ones of the most critical technical challen...

"Smartphone user tracking by incorporating user orientation using a dou" by Shuai Sun, Shaoxi Li et al.

We consider the problem of localizing a smartphone user using received signal strength (RSS) measured by a set of known network nodes in a harsh indoor environment. While the RSS of a wireless signal can be conveniently accessed, using it to estimate location is nontrivial in the presence of multipath propagation, shadowing and radio interference. Auxiliary information, such as the indoor building map and users orientation information, potentially can help to improve localization performance. As...
