DICTIONARY-LEARNING (DL)-BASED SPARSE CSI ESTIMATION IN MULTIUSER TERAHERTZ (THZ) HYBRID MIMO SYSTEMS UNDER HARDWARE IMPAIRMENTS AND BEAM-SQUINT EFFECT

This work conceives dictionary-learning (DL)-based sparse channel estimation schemes for multi-user Terahertz (THz) hybrid MIMO systems incorporating also non-idealities such as hardware impairments and beam-squint effect.Due to the presence of large antenna arrays coupled with frequency selectivity, beam squint effect is significant in THz systems

The state-of-the-art visual simultaneous localization and mapping (V-SLAM) systems have high accuracy localization capabilities and impressive mapping effects.However, most of these systems assume that the operating environment is static, thereby limiting their application in the real dynamic world.In this paper, Supporters by fusing the informatio

Persistent inflammation in end-stage renal disease (ESRD) patients is known to underlie the progression of chronic kidney disease and to be associated with multiple risk factors including malnutrition, atherosclerosis, and cardiovascular disease (CVD).The acute-phase protein pentraxin 3 (PTX3) has a proven potential as a local inflammatory biomarke

Background: Injuries due to motorcycle accidents are frequent happenings in developing countries as people utilize it commonly as a mode of transport.In Pakistan 56% of Maxillofacial injuries can be associated to Road traffic accidents (RTA) majority of which are due to involvement of Sesame Oil motorbikes.Methods: This cross sectional survey was c
