Space-Time Block Coding for Spatial Modulation
(IEEE, 2010)
Space-time block coded spatial modulation (STBC-SM) which employs space-time block coding (STBC) for spatial modulation (SM) is proposed as a new multiple-input multiple-output (MIMO) transmission scheme. In the STBC-SM ...
Joint Channel Estimation and Equalization for OFDM based Broadband Communications in Rapidly Varying Mobile Channels
(IEEE, 2010)
This paper is concerned with the challenging and timely problem of channel estimation for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying ...
Cosmic ray intensity variation during a CME
(Pergamon-Elsevier Science Ltd, 2002)
The June 6 2000 coronal mass ejection was an exceptional full halo which made it possible to measure cosmic ray (CR) decrease with a simple experimental set-up. Variation in the local secondary cosmic ray density has been ...
A Novel Image Steganography Technique based on Similarity of Bits Pairs
(IEEE, 2017)
Steganography is one of the most important information hiding mechanism which can be used along with cryptography for providing adequate data security. The common Steganographic mediums used are text image audio and video ...
Reduction of energy costs and traffic flow rate in urban logistics process
(Elsevier Science, 2017)
Energy cost is a phenomenon relating to logistics and transportation activities of logistics operators as well as governments local authorities and citizens. Actually all the logistics parties may be affected by energy ...
Beacons for Indoor Positioning
(IEEE, 2017)
This work aims to develop a system for the tracking and control of elderly or handicapped people in an indoor environment. We have developed both a special box using an Arduino board and a mobile application on Android to ...
Channel Equalization with Cellular Neural Networks
(IEEE, 2010)
In this paper a dynamic neural network structure called Cellular Neural Network (CNN) is employed for the equalization in digital communication. It is shown that this nonlinear system is capable of suppressing the effect ...
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 ...
Cascaded Lossless Commensurate Line Synthesis
(IEEE, 2009)
In this paper a synthesis algorithm for cascaded lossless commensurate lines is summarized. The algorithm is based on transfer matrix factorization. Firstly the characteristic impedance of the extracted element is calculated ...
