Contextual Preparation of Future Engineers: A non-Western Perspective
(
IEEE
, 2008 , Conference Paper)
The advent of technological communication and modern travel has increased the likelihood that graduates from engineering programs will work in environments containing integrated cultures, customs, and languages. One may ...
Distributed turbo coding using log-likelihood thresholding for cooperative communications
(
IEEE
, 2009 , Article)
In cooperative communications, error propagation at relays reduces the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is presented in ...
Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading
(
IEEE
, 2008 , Conference Paper)
Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ...
End-to-end outage probability of multihop transmission over lognormal shadowed channels
(
King Fahd University of Petroleum & Minerals
, 2003 , Article)
End-to-end outage probability evaluation of multihop wireless communication systems over lognormal shadowed channels is presented. Closed-form expression for the end-to-end signal to noise ratio of systems equipped with ...
Controlling Error Propagation in Network-Coded Cooperative Wireless Systems
(
IEEE
, 2009 , Article)
In cooperative communications, error propagation at relays degrades the diversity order of the system. To combat that effect, it has been suggested to implement a reliability threshold at the relay to control error ...
Alternative method of diffraction-enhanced imaging
(
Elsevier B.V.
, 2007 , Article)
Diffraction-enhanced imaging (DEI) is a radiographic technique that derives contrast from an object's X-ray absorption, refraction gradient and small-angle scatter properties (extinction). The DEI imaging system prepares ...
Wireless transmission using cooperation on demand
(
Elsevier B.V.
, 2009 , Article)
Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the cooperation is triggered only if the ...
Comparison of relaying strategies for cooperative diversity systems with adaptive modulation
(
IEEE
, 2009 , Conference Paper)
In this paper, we propose several relay selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes are based on dual-hop relaying with multiple relays. We analyze the performance ...
