In this paper, a frequency and radiation pattern reconfigurable Multiple Input Multiple Output (MIMO) Half Shaped Cubical Parasitic Antenna (HSCPA) is presented. 3 Planar Inverted F Antenna (PIFA) elements were used to form the HSCPA. Schottky diodes were used to perform the frequency and radiation pattern reconfiguration. The proposed HSCPA design is very versatile as it can be used to achieve multiple...
In this paper, a continuous improvement process was developed and implemented in our engineering programs at College of Engineering, Qassim University, Saudi Arabia. The continuous improvement plan was based on an integrated set of strategies aimed at: establishing and implementing a structured process that translates educational objectives into measurable outcomes, and specifies feedback tracks for...
In spite of the advancement and variety of available mobile based applications, there is an eminent need to investigate the current position of the acceptance of those mobile health applications that are tailored towards the patients' medical information management and access. This paper explores and analysis the technology acceptance of the use of smart mobile phones from users' perceptions, viewpoint,...
This paper presents a multiple-input multiple-output (MIMO) space-time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. The model is based on a one-ring scattering assumption. This MIMO model provides statistics of the time of arrival (TOA) and direction of arrival (DOA). It is assumed that there is no line of sight (LOS) between the transmitter...
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H), which is required to operate under high mobility conditions resulting in significant Inter-carrier Interference (ICI). To mitigate ICI, several cancellation schemes have been proposed but they require reliable channel information at the receiver which is quite challenging...
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H) which is required to operate under high mobility conditions resulting in significant Inter-Carrier Interference (ICI). Under these conditions, the conventional one-tap per subcarrier channel estimation and equalization is suboptimal since it does not account for ICI...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
