A Robust Localization Framework to Handle Noisy Measurements in Wireless Sensor Networks
(IEEE, 2009)
We construct a robust localization framework to handle noisy measurements in wireless sensor networks. Traditionally many approaches employ the distance information gathered from ranging devices of the sensor nodes to ...
A Simple Iterative Equalizer for Space Time Coded Multiple Antenna Systems
(IEEE, 2009)
In this paperg a simple low complexity iterative receiver for spacetime coded zSTCg transmission is proposed and the pen formance over frequencyyselective fast and quasistatic fading channels is investigatedF Simulation ...
Scaling Laws For Distributed Estimation Over Orthogonal Fading Channels
(IEEE, 2009)
We analyze the outage for distributed estimation over orthogonal fading channels as a function of the number of sensors K. We consider a scenario of fixed power per-sensor with an asymptotically large number of sensors. ...
Iterative Receiver for DS-CDMA Systems in the Presence of Time-Varying Channels
(IEEE, 2008)
In this paper we present an efficient iterative receiver structure of tractable complexity for joint multiuser detection and multichannel estimation (JDE) of direct-sequence code-division multiple-access systems operating ...
Navigation of autonomous mobile robots in connected groups
(IEEE, 2008)
The navigation of autonomous mobile robots as a group is considered in this paper. Definitions adopted from the graph theory are given to characterize the robot group. A local steering strategy is proposed such that when ...
Outage Diversity for Distributed Estimation over Parallel Fading Channels
(IEEE, 2008)
In this paper we study the outage diversity in distributed estimation over parallel fading channels. We find tight upper and lower bounds on the diversity order and show that they are arbitrarily close under certain ...
Performance of Stack Equalizer over Frequency Selective Fading Channels
(IEEE, 2008)
In this paper the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results it is illustrated that by sacrificing the computational ...
Design of mixed-element networks via modeling
(IEEE, 2008)
A new method is introduced to design mixed lumped and distributed element network
On preserving connectivity of autonomous mobile robots
(IEEE, 2009)
The connectivity of the autonomous mobile robots is considered in this paper. The group navigation is provided using simple local steering rules and without any explicit communication. Sub-optimal solutions are invoked to ...
Detection of Multiple Primary Systems Using DAA UWB-IRs
(IEEE, 2009)
Underlay ultra wideband (UWB) systems have to be able to detect the presence of primary systems operating in the same band for detect-and-avoid (DAA) operation. In this paper the performances of joint and independent ...
