Structured channel estimation algorithm based on estimating the time-of-arrivals (TOAs), with applications to digital TV receivers

SPIE Proceedings, 2003
In this paper we introduce a new structured channel impulse response (CIR) estimation method for sparse multipath channels. We call this novel CIR estimation method Time-Of-Arrival based Blended Least Squares (TOA-BLS) which uses symbol rate sampled signals, based on blending the least squares based channel estimation and the correlation and cleaning

Time of arrival (TOA)-based direct location method

2015 16th International Radar Symposium (IRS), 2015
The presented direct location method computes the 3D position of an object using exactly four time-of-arrival (TOA) measurements, i.e. range measurements, to four reference points or stations. This operation is also commonly known as multilateration. Traditionally, this problem can also be solved using three TOA measurements to three reference stations,

Performance analysis of a passive tracking filter using DOA and TOA measurements (direction of arrival/time of arrival)

Proceedings of the IEEE 1991 National Aerospace and Electronics Conference NAECON 1991, 2002
A method used for estimation of the position of a moving pulse emitter with constant pulse repeat interval by a single observer is studied. The performance of the estimator depends on the emitter trajectory. A specific trajectory that is symmetrical about the closest point of approach is considered.

An underwater sensor network localization algorithm based on Time-of-Arrivals (TOAs)

2013 Ninth International Conference on Natural Computation (ICNC), 2013
The underwater sensor network localization algorithm is one of the very important steps in the underwater sensor network initialization process. Due to the deployment of environmental constraints, the underwater sensor node can only be indirectly localized by calculation.

Direction/time of arrivals (D/TOA) estimation characteristics of the MUSIC algorithm for the actual extended targets of the chirp pulse tracking radar

Proceedings of the 2002 IEEE Radar Conference (IEEE Cat. No.02CH37322), 2003
This paper proposes the time space MUSIC technique using the chirp pulse signal of a tracking radar. Direction/time of arrival (D/TOA) estimation characteristics are evaluated for the simulated point sources, simulated extended air targets, and the actual extended air targets.

Geometric optimization of a time-of-arrival (TOA) based self-positioning terrestrial system

2011 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS 2011), 2011
This work investigates geometric optimization of antenna configuration in lateral geometry for a terrestrial time-of-arrival based self-positioning system, considering optimization confronted by two competing and opposing phenomena, the purely geometric analogy of GPS geometric dilution of precision, and tracking errors in correlation of the ...
