Comparison of relaying strategies for cooperative diversity systems with adaptive modulation
( IEEE , 2009 , Conference Paper)In this paper, we propose several relay selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes are based on dual-hop relaying with multiple relays. We analyze the performance ... -
Reflectance spectroscopy and ASTER mapping of aeolian dunes of Shaqra and Tharmada Provinces, Saudi Arabia: Field validation and laboratory confirmation
( Taylor and Francis Group , 2022 , Article)Spatial variability of grain sizes and mapping of aeolian dunes is important to study the sand erosion, transport, and dune movement and to understand the dune encroachment and land degradation. This study examines the ... -
Seismic detection and characterization of a man-made karst analog - A feasibility study
( Society of Exploration Geophysicists , 2021 , Article)At the site of a water drainage shaft on the campus of Qatar University that serves as a man-made karst analog, two seismic imaging techniques were adapted to use resonant scattered waves recorded during active-source ...
