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 ...
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 ...
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 ...
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 ...
