Exact closed-form error probability expression for cooperative diversity networks with channel estimation errors in time selective Rayleigh fading channels
(IEEE, 2010)
In this paper, we investigate the performance of a cooperative network with adaptive decode-and-forward (DF) relaying over time-selective frequency-flat Rayleigh fading channels. In adaptive DF relaying, only a subset of ...
Sualtı akustik haberleşmesi için SNR tabanlı röle seçimi kullanan işbirlikli OFDM sistemleri
(IEEE, 2012)
In this paper, we investigate a multi-carrier multi-relay cooperative system with amplify-and-forward relaying over frequency-selective underwater acoustic channels. Relay selection rules rely on the maximization of ...
Diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2015)
Network coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. In an effort to have further gains over the initial works, which build upon the assumption of ...
İşbirlikli haberleşmede birleştirilmiş zaman kayması ve sönümlemeli kanal katsayısı kestirimi
(IEEE, 2013)
In this paper, we investigate joint channel gain and time offset estimation for two different data aided methods in cooperative communication with amplify-and-forward (AF) relaying. First one is the Cascaded Estimation ...
Outage analysis of Hybrid-ARQ protocols in coherent free-space optical communications
(IEEE, 2011)
In this paper, we investigate the performance of automatic retransmission request (ARQ) protocols in coherent free-space optical (FSO) communications. Specifically, we study the outage performance of three different ...
Outage capacity and throughput analysis of multiuser FSO systems
(IEEE, 2015)
In this paper, we investigate the performance of free space optical (FSO) systems with a multiuser scheme employing select-max scheduling technique. Specifically, we consider an FSO communication system which employs a ...
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)
In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ...
Measurement of the production cross section for Z gamma -> nu(nu)over-bar gamma in pp collisions at root s=7 TeV and limits on ZZ gamma and Z gamma gamma triple gauge boson couplings
(Springer Science+Business Media, 2013-10)
A measurement of the Zγ→νν¯γ cross section in pp collisions at s√=7 TeV is presented, using data corresponding to an integrated luminosity of 5.0 fb−1 collected with the CMS detector. This measurement is based on the ...
Sparse channel estimation and equalization for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2016-01-01)
This paper is concerned with a challenging problem of channel estimation and equalization for amplifyand- forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in sparse underwater ...
A small footprint hybrid statistical/unit selection text-to-speech synthesis system for agglutinative languages
(IEEE, 2012)
Despite its success, unit selection based text-to-speech synthesis (TTS) has has some disadvantages such as sudden discontinuities in speech that distract the listeners. The HMM-based TTS (HTS) approach has been increasingly ...
