OFDM With Hybrid Number and Index Modulation
Ahmad M. Jaradat, Jehad M. Hamamreh, Huseyin Arslan
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarrie…
A comparison between MMAE and SCEM for solving singularly perturbed linear boundary layer problems
Süleyman Cengizci
In this study, we propose an efficient method so-called Successive Complementary Expansion Method (SCEM), that is based on generalized asymptotic expansions, for approximating to t…
Sparse Approximation is Provably Hard under Coherent Dictionaries
Ali Çivril
It is well known that sparse approximation problem is \textsf{NP}-hard under general dictionaries. Several algorithms have been devised and analyzed in the past decade under variou…
Dynamic Control of Interference Limited Underlay D2D Network
Yunus Sarikaya, Hazer Inaltekin, Tansu Alpcan +1
Device-to-Device (D2D) communication appears as a key communication paradigm to realizing the vision of Internet of Things (IoT) into reality by supporting heterogeneous objects in…
Structure of conflict graphs in constraint alignment problems and algorithms
Ferhat Alkan, Türker Bıyıkoğlu, Marc Demange +1
We consider the constrained graph alignment problem which has applications in biological network analysis. Given two input graphs , a pair of vertex m…
