Joint Subcarrier and Phase Shifts Optimization for RIS-aided Localization-Communication System
2022
Joint localization and communication systems have drawn significant attention due to their high resource utilization. In this paper, we consider a reconfigurable intelligent surface (RIS)-aided simultaneously localization and communication system. We first determine the sum squared position error bound (SPEB) as the localization accuracy metric for the presented localization-communication system. Then, a joint RIS discrete phase shifts design and subcarrier assignment problem is formulated to minimize the SPEB while guaranteeing each user’s achievable data rate requirement. For the presented non-convex mixed-integer problem, we propose an iterative algorithm to obtain a suboptimal solution …
Zasłużeni dla miasta. O mikrosystemie plateonimicznym Opola
2016
The Opole urban nomenclature has for many years been a space of special homage paid to the local heroes. Taking into account this fact, in my research I have concentrated on Opole streets, squares, buildings and estates named aftcr persons associated with this region. The analysis covered not only outstanding historical personalities, bul also contemporary authorities - writers, politicians and scientists. The purpose of this paper was to present the most important nomenclature trends associated with the regional history and to show the impact of names commemorating prominent historical figurcs on the contemporary image of Opole. This urban nomenclature microsystem eonsisting of about one h…
