Fault detection and isolation of linear impulsive systems
(
IEEE
, 2011 , Article)
This technical note investigates the development of fault detection and isolation (FDI) filters for linear impulsive systems. The concept of an unobservability subspace is introduced for linear impulsive systems and an ...
Efficient online WiFi delivery of layered-coding media using inter-layer network coding
(
IEEE
, 2011 , Conference Paper)
A primary challenge in multicasting video in a wireless LAN to multiple clients is to deal with the client diversity - clients may have different channel characteristics and hence receive different numbers of transmissions ...
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 ...
Characterization of the indoor-outdoor radio propagation channel at 2.4 GHz
(
IEEE
, 2011 , Conference Paper)
We present the site-specific signal strength measurement results for path loss, shadowing, and fading in 2.4GHz band under typical harsh environment (high temperature 4050 C and humidity 8090%). We use spectrum analyzer ...
Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
(
IEEE
, 2011 , Conference Paper)
We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ...

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 ...
Joint routing and resource allocation for delay sensitive traffic in cognitive mesh networks
(
IEEE
, 2011 , Conference Paper)
In this paper we study the problem of joint design of routing and resource allocation in cognitive radio based wireless mesh networks. Our study focuses on a cognitive system model in which secondary nodes have delay ...
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 ...
Exposure assessment to WiFi access points by simulations and measurements
(
IEEE
, 2011 , Conference Paper)
This paper discusses two different approaches to assess exposure to indoor WiFi access points at two different frequency bands: 2.4GHz and 5GHz. The first analyzes the electromagnetic propagation in almost empty environments ...
