Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008)In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ... -

Design of broadband microwave amplifiers with mixed-elements via reflectance data modeling
(Elsevier GMBH Urban & Fischer Verlag, 2008)A practical method is introduced to design single-stage broadband microwave amplifiers with mixed lumped and distributed elements via modeling the reflectance data obtained from lumped-element input and output matching ... -
Design of broadband single matching networks
(Elsevier GMBH Urban & Fischer Verlag, 2009)In general commercially available software tools are preferred to design broadband matching networks for wireless communication systems. But they need a properly selected matching network topology with good initial element ... -
Design of distributed-element RF filters via reflectance data modeling
(Elsevier GMBH Urban & Fischer Verlag, 2008)A reflectance-based modeling method is presented to obtain the distributed-element counterpart of a lumped-element network which is described by measured or computed reflectance data at a set of frequencies. Numerical ... -
Design of low-pass ladder networks with mixed lumped and distributed elements by means of artificial neural networks
(AVES YAYINCILIK, 2003)In this paper, calculation of parameters of low-pass ladder networks with mixed lumped and distributed elements by means of artificial neural networks is given. The results of ANN are compared with the values that are ... -
Design of mixed-element networks via modeling
(IEEE, 2008)A new method is introduced to design mixed lumped and distributed element network -
The design of potent HIV-1 integrase inhibitors by a combined approach of structure-based virtual screening and molecular dynamics simulation
(Taylor & Francis Ltd, 2018)Bu araştırmanın amacı, AIDS olarak bilinen insan bağışıklık sistemine etki eden, duraksamayan ve depresif bir hastalığa neden olan HIV-1'in tedavisi için potansiyel inhibitörleri elde etmektir. HIV-1 integraz inhibitörleri, ... -
Design of practical broadband matching networks with commensurate transmission lines
(Elsevier GMBH Urban & Fischer Verlag, 2013)To design broadband matching networks for microwave communication systems commercially available computer aided design (CAD) tools are always preferred. But these tools need proper matching network topology and element ... -
Design of Practical Broadband Matching Networks With Lumped Elements
(IEEE-INST Electrical Electronics Engineers Inc, 2013)It is always preferable to use commercially available software tools to design broadband matching networks for microwave communication systems. However for these tools the matching network topology and element values must ... -
Design of Practical Broadband Matching Networks With Mixed Lumped and Distributed Elements
(IEEE-INST Electrical Electronics Engineers Inc, 2014)Computer-aided design (CAD) tools are always preferred for designing broadband matching networks. However these tools give excellent results when the suitable matching network topology and initial element values are provided. ... -
Design of practical matching networks with lumped elements via modeling
(IEEE, 2007)It is a common practice to utilize commercially available software tools to design matching networks for wireless communication systems. Most of these tools require a properly selected matching network topology with good ... -
Design, Synthesis and In Vitro Cytotoxic Activity of New 6,9-Disubstituted Purine Analogues
(Slovensko Kemijsko Drustvo, 2020)A series of new 6,9-disubstituted purine analogs with 4-substituted piperazine at C-6 and 4-substituted benzyl at N-9 were designed and synthesized in four steps. All synthesized compounds (7-26) were screened initially ... -
Detection of interdependent primary systems using wideband cognitive radios
(Elsevier GMBH Urban & Fischer Verlag, 2013)Cognitive radios (CRs) may be sharing multiple frequency bands with primary systems if the CR is a wideband or an ultra wideband (UWB) system. In that case the CR should ensure all the coexisting primary systems in these ... -
Detection of jointly active primary systems
(IEEE, 2012)Recent studies in cognitive radios consider the detection of multiple bands for a better utilization of the spectrum. If the cognitive radio (CR) is an ultra wideband (UWB) or a wideband system then the CR should ensure ... -
Detection of Multiple Primary Systems Using DAA UWB-IRs
(IEEE, 2009)Underlay ultra wideband (UWB) systems have to be able to detect the presence of primary systems operating in the same band for detect-and-avoid (DAA) operation. In this paper the performances of joint and independent ... -
