Aspects of Geo-Location in Mobile Networks

Geo-location for voice search language modeling

We investigate the benefit of augmenting with geo-location information the language model used in speech recognition for voice-search. We observe reductions in perplexity of up to 15% relative on test sets obtained from both typed query data, as well as transcribed voice search data; on a subset of the test data consisting of “local” queries — search results displaying a restaurant, some addres...

Modelling Geo Data for Location-based Services

Ubiquitous indoor wireless geo-location system

Positioning systems are an established need in the current world. The ability to identify the position of a given object in a given context is a common service in our fast-paced, online and always-connect global community. For normal day-to-day usage outdoor systems have a matured and integrated usage, from destination guidance to social media applications status updates, all can use the curren...

Geo-Location Using Direction Finding Angles

254 INTRODUCTION The detection, classification, and geo-location of ground-based signal sources is one of the primary missions of modern military surveillance aircraft. Example signals of interest are the search radar of an enemy missile site, the radio communications between enemy combatants, and the distress radio beacon being transmitted by a downed friendly pilot. The ability to locate such...
