Simulation of Lightning Flash in Time of Arrival (TOA) Method by Using Three Broadband Antennas

2011 UKSim 5th European Symposium on Computer Modeling and Simulation, 2011
Various methods are used to locate cloud-to-ground lightning flash. The accuracy of the methods depends on the number of sensor stations, station topology, mathematical model adopted for the analyses, and type of measuring equipment. For a single station with the configuration of short baseline in a measuring system, the accuracy analysis is mostly ...

Time-of-arrival (TOA) estimation based structured sparse channel estimation algorithm, with applications to digital TV receivers

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004
We introduce a new structured channel impulse response (CIR) estimation method for sparse multipath channels where we demonstrate a robust way of restoring the pulse shape into the composite CIR. We call this novel CIR estimation method time-of-arrival based blended least squares (TOA-BLS) which uses symbol rate sampled signals, and it is based on ...
