Busy Tone Based Power Control for Coordination of IFFY 802.11af and 802.22 System
(IEEE, 2017)
In this paper, a new power control algorithm based on busy tone approach has been proposed for the coordination of IEEE 802.22 and IEEE 802.11af systems in TV white space. Different from the earlier studies, in addition ...
Realistic Channel Estimation of IEEE 802.11af Systems in TV White Space
(Institute of Electrical and Electronics Engineers Inc., 2020)
This work investigates the realistic performance of IEEE 802.11af systems released for the efficient spectrum utilization of TV white space (TVWS). These systems are operated over many contiguous or non-contiguous channels ...
Physical-layer security in visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2020)
Optical wireless communications (OWC) and its potential to solve physical layer security (PLS) issues are becoming important research areas in 6G communications systems. In this paper, an overview of PLS in visible light ...
Enerji Verimli İletişim Sistemlerinin Tasarımı için Sıkıştırılmış Algılama Tabanlı Yaklaşımlar
(2016)
Sıkıstırılmıs Algılama (Compressed Sensing, CS) teorisi, isaretin seyrek bölgede tanımlanabildigi durumlarda Nyquist hızından çok daha düsük hızlarda örneklenen isaretin basarılı bir sekilde geri kazanılabilecegi gerçegine ...
