Type Parameters:
S - a RadioSource type.
public class PROSACRobustRssiRadioSourceEstimator3D<S extends RadioSource> extends RobustRssiRadioSourceEstimator3D<S>
Robustly estimate 3D position, transmitted power and path-loss exponent of a radio source (e.g. Wi-Fi access point or bluetooth beacon), by discarding outliers using PROSAC algorithm and assuming that the access point emits isotropically following the expression below: Pr = Pt*Gt*Gr*lambda^2 / (4*pi*d)^2, where Pr is the received power (expressed in mW), Gt is the Gain of the transmission antenna Gr is the Gain of the receiver antenna d is the distance between emitter and receiver and lambda is the wavelength and is equal to: lambda = c / f, where c is the speed of light and f is the carrier frequency of the radio signal. Because usually information about the antenna of the radio source cannot be retrieved (because many measurements are made on unknown access points where physical access is not possible), this implementation will estimate the equivalent transmitted power as: Pte = Pt * Gt * Gr. If RssiReadings contain RSSI standard deviations, those values will be used, otherwise it will be assumed an RSSI standard deviation of 1 dB. Implementations of this class should be able to detect and discard outliers in order to find the best solution.

IMPORTANT: When using this class estimation can be done using a combination of radio source position, transmitted power and path loss exponent. However enabling all three estimations usually achieves inaccurate results. When using this class, estimation must be of at least one parameter (position, transmitted power or path loss exponent) when initial values are provided for the other two, and at most it should consist of two parameters (either position and transmitted power, position and path loss exponent or transmitted power and path loss exponent), providing an initial value for the remaining parameter.

      threshold - threshold to determine whether samples are inliers or not.
      Throws:
      IllegalArgumentException - if provided value is equal or less than zero.
