First, let us consider the communication performances of the direct links between source and destination nodes through BER measurements.
The image reconstruction problem involves relating measurements between source and detector pairs and the unknown quantity of interest in the volume with mathematical models of photon transport in tissue, and then solving the subsequent inverse problem [ 9].
Bletsas et al. [5] devise a novel scheme that selects the best relay between source and destination based on instantaneous channel measurements to reduce the outage probability.
During measurement, the applied voltage between source and drain is kept constant at 1 V.
A widely acknowledged measurement of system security in WRNs is the maximal rate of secret information exchange between source and destination which is defined as secrecy capacity.
It is found that significant deviation exists between sources, and that all ground-station measurements display unknown uncertainty levels, thus highlighting the need for a proper, country-wide long-term resource assessment initiative.
Under the influence of different measurement methods between sources and terminals as well as the impact of process technology, process parameters, process loss and environmental changes, the error of inventory reconciliation obeys the normal distribution that the mean is not zero actually.
The propagation model establishes a relationship (referred to as weight functions) between the excitation source and the measurement collected by the emission detector, based on the model geometry and optical properties.
We therefore investigate the probe-like geometry for reflectance measurements characterized by small distances between sources and detectors.
Overall, in Eq. (2), y represents the vector of measured optical densities, as defined by -log(φ/φ 0), between all possible pairs of sources and detectors at the measurement boundary and has the size of NM × 1, where NM is the number of measurements (or all possible combined pairs between sources and detectors).
