VLSI implementation of GRBF (Gaussian Radial Basis Function) networks
(IEEE, 2000)
A GRBF network is designed for VLSI implementation. Building blocks of the network consist mainly of analog circuits: op-amp multiplier multiplying DAC (digital to analog converter) floating resistor summer and exponentiator. ...
Broadband double-matching via lossless unsymmetrical lattice networks
(Istanbul University, 2012)
In this paper a broadband double-matching network design algorithm has been presented. In the network an unsymmetrical lattice network has been used. The branch impedances of the lattice network are composed of singly ...
Guest editorial: special issue on high mobility wireless communications

A Monte Carlo implementation of the SAGE algorithm for joint soft-multiuser decoding channel parameter estimation and code acquisition
(2010)
This paper presents an iterative scheme for joint timing acquisition multi-channel parameter estimation and multiuser soft-data decoding. As an example an asynchronous convolutionally coded direct-sequence code-division ...
A low-complexity KL expansion-based channel estimator for OFDM systems
(2005)
This paper first proposes a computationally efficient pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach employs ...
Synthesis of resistively terminated LC ladder networks
(Istanbul University, 2011)
In this work element value calculation algorithms have been proposed for low-pass high-pass band-pass and band-stop LC ladder networks. According to the calculated constant from the given transfer scattering matrix the ...
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 ...
Shifted-modified Chebyshev filters
(TUBITAK Scientific & Technical Research Council Turkey, 2013)
This paper introduces a new type of filter approximation method that utilizes shifted-modified Chebyshev filters. Construction of the new filters involves the use of shifted-modified Chebyshev polynomials that are formed ...
Channel Estimation for Realistic Indoor Optical Wireless Communication in ACO-OFDM Systems
(Springer, 2018)
In this paper channel estimation problem in a visible light communication system is considered. The information data is transmitted using asymmetrical clipped optical orthogonal frequency division multiplexing. Channel ...
New Trellis Code Design for Spatial Modulation
(IEEE-INST Electrical Electronics Engineers Inc, 2011)
Spatial modulation (SM) in which multiple antennas are used to convey information besides the conventional M-ary signal constellations is a new multiple-input multiple-output (MIMO) transmission technique which has recently ...
