Application of a Virtual Magnetic Dipoles in Antenna Array to Increase the Direction Finding Accuracy

Direction Finding Algorithm with Virtual Antenna Array

Background: Direction finding (DF) based on MUSIC algorithm has been studied and implemented in the wireless communications lab. Simulation results, measurement setup are shown in the figures below. Most of the direction finding (DF) algorithms require multiple antennas with at least í µí¼†/2 spacing. Also, performance of the DF algorithms mainly relies on  Number of antennas in the antenna ar...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

An Accurate Direction Finding Scheme Using Virtual Antenna Array via Smartphones

With the development of localization technologies, researchers solve the indoor localization problems using diverse methods and equipment. Most localization techniques require either specialized devices or fingerprints, which are inconvenient for daily use. Therefore, we propose and implement an accurate, efficient and lightweight system for indoor direction finding using common smartphones and...

A Hybrid Intelligent Model to Increase the Accuracy of COCOMO

Nowadays, effort estimation in software projects is turned to one of the key concerns for project managers. In fact, accurately estimating of essential effort to produce and improve a software product is effective in software projects success or fail, which is considered as a vital factor. Lack of access to satisfying accuracy and little flexibility in existing estimation models have attracted ...
