(The Electromagnetics Academy, 2012-03)A novel compact tree-design antenna (NCTA) with the ability of reconfigurable ultra-wideband (UWB) of 3.1 GHz to 10.6 GHz to five multi-narrowband applications is proposed. This antenna has a novel radiating element design ... -
A reconfigurable WiMAX antenna for directional and broadside application
(Hindawi Publishing Corporation, 2013)A novel reconfigurable compact patch array antenna for directional and broadside application is proposed. The presented antenna has successfully been able to function for directional beam at 320° or 35° and divisive broadside ... -
Redesign the 4:2 compressor for partial product reduction
(International Association of Science and Technology for Development (IASTED) / ACTA Press, 2007)In this paper, we attempt to redesign the 4:2 compressors. Since its inception by Weinberger in 1981[1], this concept of compressor has been used in most digital multiplications and multi operand operation scheme. The ... -
Reduced complexity optimum detector for block data transmission systems
(The Institute of Electronics, Information and Communication Engineers, 2009-12-10)Block Data Transmission Systems (BDTS) are used in high-speed wireless communication systems with time dispersive channel characteristics. In such systems, blocks of data are separated by zeros to mitigate the effect of ... -
Reducing BER of spectral-amplitude coding optical code-division multiple-access systems by single photodiode
(European Optical Society, 2013)In this paper, we present a single photodiode detection (SPD) technique for spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. The proposed technique eliminates both phase-induced intensity ... -
