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 ...
Chip-Level Modulated BPPM Fiber-Optic Code Division Multiple Access
(
IEEE
, 2009 , Conference Paper)
Chip-Level Modulated Binary Pulse Position Modulation (CLM-BPPM) is proposed as a modulation scheme for Fiber-Optic Code Division Multiple Access (FO-CDMA) systems using Optical Orthogonal Code (OOC) for time domain signal ...
A predictive strategy for lifetime maximization in selective relay networks
(
IEEE
, 2009 , Conference Paper)
Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ...
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 ...
Performance of relay-assisted soft handover
(
IEEE
, 2009 , Conference Paper)
This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ...
Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference Paper)
Multihop transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several, possibly shorter links/hops. This paper presents an expression for the moment ...
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 ...
Performance enhancement of relay-assisted communications via binary feedback
(
IEEE
, 2004 , Conference Paper)
This paper proposes a modified two-hop wireless communication system and studies its performance. The modified system has a reliable feedback channel that carries a binary signal from the receiver to inform the transmitter ...
Research in undergraduate education at Qatar University: EE department experience
(
IEEE
, 2007 , Conference Paper)
This paper presents the research efforts taking place at Qatar University, the only national university in Qatar. Being a teaching institute, conducting research faces many challenges. The paper focuses on the experience ...
On the capacity of cooperative diversity systems with adaptive modulation
(
IEEE
, 2005 , Conference Paper)
In recent years, cooperative diversity systems have gained increased attention in the literature as a new way of combating the effect of signal fading. In this paper, we investigate the performance of these systems when ...
