Iterative channel estimation for spatial modulation systems over fast fading channels
(IEEE, 2014)
Spatial Modulation (SM) based on the use of antenna indices to transmit information in addition to the conventional signal constellations has been recently proposed to solve practical problems encountered in MIMO systems. ...
Partial Power and Rate Adaptation for MQAM/OFDM Systems under CFO
(IEEE, 2014)
In this paper a new partial power and rate adaptation scheme for orthogonal frequency division multiplexing (OFDM) systems is proposed in the presence of carrier frequency offset (CFO). The conventional adaptive scheme is ...
Outage Probability of a Cooperative Maximum Ratio Transmission
(IEEE, 2014)
In this paper we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve ...
Collectivity in Heavy Nuclei in the Shell Model Monte Carlo Approach
(EDP Sciences, 2014)
The microscopic description of collectivity in heavy nuclei in the framework of the configuration-interaction shell model has been a major challenge. The size of the model space required for the description of heavy nuclei ...
IEEE 802.15.4a Based Ultra Wideband Systems for Coexistence with Primary Users
(IEEE, 2015)
Peaceful coexistence is a major implementation issue for both cognitive radios and ultra wideband (UWB) systems. Accordingly the UWB impulse radio (UWB-IR) based Wireless Personal Area Network (WPAN) standard IEEE 802.15.4a ...
Improving OpenCL programmability with the Heterogeneous Programming Library
(Elsevier Science Bv, 2015)
The use of heterogeneous devices is becoming increasingly widespread. Their main drawback is their low programmability due to the large amount of details that must be handled. Another important problem is the reduced code ...
Contraction Blockers for Graphs with Forbidden Induced Paths
(Springer-Verlag Berlin, 2015)
We consider the following problem: can a certain graph parameter of some given graph be reduced by at least d for some integer d via at most k edge contractions for some given integer k? We examine three graph parameters: ...
Analysis of Extended Busy Tone Performance for Coexistence between WRAN and WLAN TVWS Networks
(IEEE, 2015)
TV White Spaces indicate spectrum bands which were reserved for licensed terrestrial TV broadcasting and opened to unlicensed use under regulatory conditions. One important regulation which is common in all regulatory ...
Low Energy Fixed Clustering Algorithm (LEFCA) for Wireless Sensor Networks
(IEEE, 2015)
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 ...
Pilot Symbol Assisted Channel Estimation for 4x4 Space Time Block Coded Spatial Modulation Systems
(IEEE, 2015)
Recently spatial modulation (SM) and space-time block coding (STBC) are combined to take advantage of the benefits of both while avoiding their drawbacks for multiple-input and multiple-output (MIMO) systems. The pioneering ...
