On the Geolocation Bounds for Round-Trip Time-of-Arrival and All Non-Line-of-Sight Channels
EURASIP Journal on Advances in Signal Processing, 2007 The development of future geolocation systems requires a fundamental understanding of the importance of various system parameters, such as the number of sensors, the SNR, bandwidth, and channel conditions. We consider the bounds on time-based geolocation

Hybrid TOA/AOA Approximate Maximum Likelihood Mobile Localization
Journal of Electrical and Computer Engineering, 2010 This letter deals with a hybrid time-of-arrival/angle-of-arrival (TOA/AOA) approximate maximum likelihood (AML) wireless location algorithm. Thanks to the use of both TOA/AOA measurements, the proposed technique can rely on two base stations (BS) only ...
