Channel assignment of microcellular mobile radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2006 , Conference)
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 ...
Power loading algorithms for SEC diversity schemes
(
IEEE
, 2007 , Conference)
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 ...
Average outage duration of multihop communication systems with regenerative relays
(
IEEE
, 2005 , Article)
Closed-form expressions for the average outage duration (AOD) of multihop regenerative communication systems over generalized fading channels are presented. Both noise-limited and interference-limited systems are studied. ...
On the capacity of cooperative diversity systems with adaptive modulation
(
IEEE
, 2005 , Conference)
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 ...
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 ...
Optimal power allocation for relayed transmissions over Rayleigh-fading channels
(
IEEE
, 2004 , Article)
Relayed transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several shorter links/hops. One of the main advantages of this communication technique ...
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 ...
Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference)
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 ...
Performance of OFDM with M-QAM modulation and optimal loading over rayleigh fading channels
(
IEEE
, 2004 , Conference)
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 ...
Performance enhancement of relay-assisted communications via binary feedback
(
IEEE
, 2004 , Conference)
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 ...
