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 ...
User cooperation schemes in the soft handover regions
(
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 ...
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 ...
