To improve the reliability and the accuracy of remote positioning - a method by estimating the rice - factor of a radio link

摘要

Device for determining the quality of a radio link, in which the propagation of the radio signals by means of a plurality of propagation paths is effected, with:– an estimator for estimating a parameter, which is characteristic for the thickness of a connection path by means of a point of view of the transmitted signal with respect to the thickness of the through not - point of view of connection paths transmitted signals, wherein the distribution function for the signal amplitude of a rice - distribution is assumed and the characteristic parameters of the rice - factor (k) is,characterized in thatsaid estimating means includes is configured to the rice - factor corresponding to to estimate, wherein r is the amount of the sampling values of the complex reception signal, and ê {x} by means of a running average value of x is approached.
