There is provided a method and/or an apparatus for time of arrival, TOA, measurements. One method includes: performing, at a sample resolution, a correlation process on a received measurement signal to achieve a measurement correlation function; determining a peak sample and correlation data of ...
Time difference of arrival measurement system A method and apparatus for measuring the time difference of arrival between two received signals, each received signal being a time delayed version of a transmitted signal as intercepted at two different sensors where the transmitted sig...

An attempt is made to understand the characteristics of pulsar slowdown in terms of various possible emission mechanisms. Though magnetic-dipole radiation seems to be dominant, the deviations from a pure dipolar decay are large compared with errors in measurement and indicate the presence of more ...
A comparison in terms of ranging accuracy, complexity, and parameters sensitivity to propagation conditions is carried out also considering a conventional technique based on threshold detection. In particular, the algorithms are tested on experimental data collected from a measurement campaign performed in...
With respect to the second drawback of TOA, the transmitted signal from the target node in TDOA need not contain a time stamp, since a single TDOA measurement is the difference in the arrival time at the respective base nodes. This simplifies the structure of transmitted signals and removes ...
Time of arrival matrices were established from this including Gaussian distributed noise to use as input to the model. This represents an optimal dataset in which all transmissions are registered as straight line detections with Gaussian distributed observation noise corresponding to hardware measurement ...
location as a timing reference. We present a brief theoretical background and describe the measurement process which includes several approaches that correct the timing and frequency errors between the receivers. Additionally, we have implemented an angle of arrival direction finder using coherent rtl-...
In the first method, each receiver measures the absolute time instant of signal arrival (time-of-arrival or TOA) as defined by ti above. A difference in time-of-arrivals between two receivers is then calculated to obtain the TDOA measurement. This method is applicable when certain signal ...

the wireless signal for which timing data must be carefully measured and also ambient light that may act as noise to the signal measurement. As such, an optical distance measurement system relying on a single received signal may perform sub-optimally if the wireless signal to be timed is weak...
