Sparse channel estimation and data detection algorithms for ofdm-based underwater acoustic communication systems
(Kadir Has Üniversitesi, 2018)
Communication over acoustic signals in underwater results into a multi-scale multilag channels which occurs due to the multipath propagation. Hence a robust channel estimation technique has to be present at the receiver ...
Low energy fixed clustering algorithm for wireless sensor networks
(Kadir Has Üniversitesi, 2016)
Wireless sensor networks (WSNs) have become an important part of our lives as they can be used in vast application areas from disaster relief to health care. As a consequence the life span and the energy consumption of a ...
Performance analysis of low complexity maximal ratio transmission approaches in multi-relay networks
(Kadir Has Üniversitesi, 2014)
Kablosuz ileti sim a ğlarının artan talebi karşılamak için yüksek veri hızına sahip, yüksek güvenilirlikli ve düşük enerji tüketimli olması gerekmektedir. Bu nedenle, bu doktora tezi düşük karmaşıklığa sahip kuvvetlendir-aktar ...
Multi-sensor indoor positioning
(Kadir Has Üniversitesi, 2022-01)
In this study, multi-sensor indoor positioning methods, which fuse the tri-laterated position data of the target are considered. The lateration is based on the dis tances that are obtained using the signal strengths received ...
