On the fairness of frequency domain resource allocation in Wireless Mesh Networks A survey
(
IEEE
, 2011 , Conference Paper)
This article presents a concise survey of fairness-aware frequency domain resource allocation techniques in Wireless Mesh Networks (WMNs). Wireless mesh networks have emerged as a key technology for next generation application ...
Performance analysis for truncated ARQ based DSFBC-CO-OFDM communication scheme
(
IEEE
, 2011 , Conference Paper)
We develop and analyze an ARQ (Automatic Repeat reQuest) based distributed space-frequency block code-orthogonal frequency division multiplexing protocol for cooperative communications (DSFBC-CO-OFDM). At PHY layer, space ...
Noisy zones of proximal development: Conversation in noisy classrooms
(
Blackwell Publishing Ltd

Biological control of Botrytis cinerea using the antagonistic and endophytic Burkholderia cepacia Cs5 for vine plantlet protection
(
Canadian Science Publishing
, 2011 , Article)
Antifungal activity of the Burkholderia cepacia Cs5 was tested in vitro and in vivo for the control of Botrytis cinerea . Bacterial biomass was significantly improved by the amendment of ZnSO(4), Mo(7)(NH(4))(6)O(24), and ...
Kalman filter-based time-varying cortical connectivity analysis of newborn EEG
(
IEEE
, 2011 , Conference Paper)
Multivariate Granger causality in the timefrequency
domain as a representation of time-varying cortical
connectivity in the brain has been investigated for the adult
case. This is, however, not the case in newborns as ...
Joint statistics of partial sums of ordered exponential variates and performance of GSC RAKE receivers over rayleigh fading channel
(
IEEE
, 2011 , Article)
Spread spectrum receivers with generalized selection combining (GSC) RAKE reception were proposed and have been studied as alternatives to the classical two fundamental schemes: maximal ratio combining and selection combining ...

Effect of high-velocity scenarios on the performance of MIMO LTE packet scheduling
(
IEEE
, 2011 , Conference Paper)
In this paper we analyze the performance of advanced OFDM packet scheduling techniques based on 3GPP UTRAN Long Term Evolution (LTE) framework for high velocity scenarios. Based on our previous investigations in system ...
The impact of inter-layer network coding on the relative performance of MRC/MDC WiFi media delivery
(
ACM
, 2011 , Conference Paper)
A primary challenge in multicasting video in a wireless LAN is to deal with the client diversity - clients may have different channel characteristics and hence receive different numbers of transmissions from the AP. A ...
