Mitigation of multipath fading in indoor radiometric fingerprinting systems

Indoor Localization based on Multipath Fingerprinting

In recent years there has been a growing interest in position location in indoor venues. As more applications requiring indoor localization are emerging in the market, the demand for accurate and reliable localization increases. Unfortunately, the accuracy of available techniques is limited, and a dense and expensive deployment is required. The problem of accurate indoor localization is challen...

Locata’s VRayTM Antenna Technology – Multipath Mitigation for Indoor Positioning

VRayTM antenna technology developed by the Locata Corporation, is demonstrating unprecedented highaccuracy positioning under extreme multipath conditions especially in indoor environments. This new technology is an extremely flexible and adaptable foundation platform upon which many variations can be built for different uses. It therefore offers a new suite of technology solutions which will al...

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

INDOOR NAVIGATION SYSTEMS BASED ON iBEACON FINGERPRINTING

Multipath & Fading

In radar processing, multipath causes ghost targets to appear, deceiving the radar receiver. These ghosts are particularly bothersome since they move and behave like the normal targets (which they echo), and so the receiver has difficulty in isolating the correct target echo. These problems can be overcome by incorporating a ground map of the radar's surroundings and eliminating all echoes whic...
