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 ...
Distributed estimation over parallel fading channels with channel estimation error
(IEEE, 2008)
We consider distributed estimation of a source observed by sensors in additive Gaussian noise where the sensors are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a ...
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
Effect of the Channel Estimation Error on the Performance of the Source Estimator in a Wireless Sensor Network with Orthogonal Channels
(IEEE, 2008)
In this work effect of the channel estimation error on the MSE performance of the source estimator in a wireless sensor network with orthogonal flat fading channels is studied. A two-phase approach was employed where in ...
Dynamic Priority Packet Scheduler with Deadline Considerations (DPD)
(INT INST Informatics & Systemics, 2010)
Providing quality of service (QoS) to applications with different traffic characteristics based on their needs is an important research area for today's and tomorrow's high speed networks. Various techniques have been ...
Joint Data Detection and Channel Estimation for OFDM Systems in the Presence of Very High Mobility
(IEEE, 2009)
This paper is concerned with the challenging and timely problem of joint channel estimation and data detection for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ...
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 ...
Linear Combination of Pulses for Coexistence in the IEEE 802.15.4a Standard
(IEEE, 2009)
The low data rate accurate location ranging Wireless Personal Area Network zWPAN standard IEEE which is based on ultra wideband zUWBg impulse radios suggests using linear combination of pulses to reduce interference to ...
