Whitepaper: MUSIC for OFDM by Using an Uniform Antenna Array With Two Elements

by Universite LavalJan 01, 2008

MUSIC, Multiple Signal Classification proposed is one of famous subspace based array processing to DOA estimation (Direction of Arrival) and even strength, polarization characteristic of the incoming signal. In MUSIC, for point source the auto covariance matrix of incoming signals on antenna array is considered. The rank of that matrix depends on number of array elements corresponding to number of independent uncorrelated inputs. In this paper, the problem of DOA estimation for OFDM using an


Whitepaper: Geospatial Service Oriented Architectures for Mobile Augmented Reality

by Universite LavalJan 01, 2008

This research paper illustrates the concept of Geospatial Service Oriented Architectures (GeoSOA) and its relevance in the definition of distributed and interoperable multi-representation data infrastructures to enhance the experience of the users in mobile augmented reality applications. This visualization mode of information is more natural for a user because it better corresponds to its perception of a real environment. Web Service provided by the W3C (W3C, 2004), A Web Service is a software
