End-to-end performance of transmission systems with relays over Rayleigh-fading channels
(
IEEE
, 2003 , Article)
End-to-end performance of two-hops wireless communication systems with nonregenerative relays over flat Rayleigh-fading channels is presented. This is accomplished by deriving and applying some new closed-form expressions ...
Power loading algorithms for SEC diversity schemes
(
IEEE
, 2007 , Conference Paper)
Switch and Examine Combing (SEC) diversity scheme is one of the simplest diversity schemes to combat fading. When the power used for probing the channels in this scheme is fixed, it can be higher than what is actually ...
Performance of OFDM with M-QAM modulation and optimal loading over rayleigh fading channels
(
IEEE
, 2004 , Conference Paper)
We present optimum bit and power loading algorithms for orthogonal frequency division multiplexing (OFDM) systems using an M-ary quadrature amplitude modulation (M-QAM) scheme. Several scenarios for the amount of channel ...
Channel assignment of microcellular mobile radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2006 , Conference Paper)
This paper addresses the analytical and simulation modeling of non overlapping microcells with both non-prioritized and prioritized handover schemes. The network performance is analyzed in terms of the analytical results ...
A performance study of dual-hop transmissions with fixed gain relays
(
IEEE
, 2004 , Article)
This letter presents a study on the end-to-end performance of dual-hop wireless communication systems equipped with nonregenerative fixed gain relays and operating over flat Rayleigh-fading channels. More specifically, it ...
Development of a remote lab for electrical engineering program
(
IEEE Computer Society
, 2009 , Conference Paper)
A remote lab for electrical engineering experiments has been designed and implemented. This has been intended as a platform that supports existing traditional labs by offering lab experiments that serve some of the student ...
Writer identification using edge-based directional probability distribution features for Arabic words
(
IEEE
, 2008 , Conference Paper)
A system for writer identification based on Arabic handwritten words was built. First a database of words was gathered and used as a test base. Then, features vectors were extracted from writers' word images. Prior to ...

Recognition of off-line handwritten Arabic words using neural network
(
IEEE
, 2006 , Conference Paper)
Neural network (NN) have been used with some success in recognizing printed Arabic words. In this paper, a complete scheme for unconstrained Arabic handwritten word recognition based on a Neural network is proposed and ...
