Space time turbo coded OFDM system with transmit and receive antenna selection
(IEEE, 2011)
In this paper a space-time turbo coded (STTC) orthogonal frequency division multiplexing (OFDM) system with QPSK signalling is explored when joint transmit and receive antenna selection is employed. Maximization of signal ...
Realization of ideal filter characteristics via genetic algorithm
(2011)
In this paper realization of ideal filter characteristics via genetic algorithm has been studied. The filter is defined as a lossless two-port terminated normalized source and load resistances and the coefficients of its ...
Routing performance analysis of opportunistic networks with flooding and partial flooding methods [Fırsatçı a?larda taşırma ve kısmi taşırma yöntemleriyle yönlendirme performans analizi]
(IEEE, 2012)
Opportunistic networks is one of the fast developing research areas in mobile communications. Under opportunistic networks mobile nodes try to communicate with other nodes without any prior information and knowledge about ...
The effect of secondary user locations on the cooperative detection performance [İki?nci?l kullanıcı konumlarının i?şbi?rli?kli? algılama yöntemi? performansına etki?si?]
(IEEE, 2012)
In conventional cooperative detection a fusion center decides on the presence or absence of the primary user by gathering all the information from secondary users and conveys this decision to all users. This approach does ...
Parallel-in-space implementation of transient stability analysis on a Linux cluster with infiniband
(IEEE, 2012)
On-line transient stability analysis is an inevitable way to provide real time power system security and control. Parallel computing is one of the most viable ways to perform on-line transient stability analysis. This paper ...
Effects of channel models and optional data rates on the IEEE 802.15.4a system performance [Kanal modellerinin ve seçime bağli veri hızlarının IEEE 802.15.4a sistem başarımına etkileri]
(2010)
The wireless personal area network standard IEEE 802.15.4a uses ultra wideband impulse radios (UWB-IRs) for precise ranging and location and as well as for communications at low data rates (about 1 Mb/s). In addition to ...
Joint phase noise estimation and source detection [Ortak faz gürültüsü kestirimi ve kaynak sezimlemesi]
(2010)
Rapidly time-varying and random disturbing effects on the phase of a signal waveform are known as phase noise. In this paper we consider the problem of joint detection of continuous-valued information source output and ...
Synthesis of resistively terminated high-pass LC ladder networks [Direnç ile sonlandırılmış yüksek geçiren LC merdiven devrelerin sentezi]
(2010)
In this paper a transfer matrix factorization based synthesis algorithm for resistively terminated high-pass LC ladder networks is presented. In the algorithm component value of the extracted element and the scattering ...
Electromagnetic interactions of heavy ions at small impact parameters and lepton pair productions
(Institute of Physics Publishing, 2011)
In peripheral collisions the strong electromagnetic fields are produced since the fully stripped heavy ions moves at ultra-relativistic velocities. Lepton pairs especially the electron-positron pairs are the result of this ...
The effect of channel resolution on compressed sensing based Ultra-Wideband channel estimation [Kanal çözünürlü?ünün sıkıştırılmış algılama tabanlı ultra geni?ş bantlı kanal kesti?ri?mi?ne etki?si?]
(2011)
Ultra short pulses are transmitted in Ultra-Wideband (UWB) communications. As a result of this pulses at the receiver can be resolved individually due to the sparse structure of the channel. Due to these properties the UWB ...
