Minimization of the Prediction Error of the Radio Communication Channel State Using Adaptive Setting of Prediction Range

Abstract

Adaptive setting of the radio signal envelope multipath propagation. The envelope of the received prediction range according to the mobile station speed signal has Rayleigh probability distribution [2]. The has to ensure minimization of the prediction error while simulated Rayleigh fade envelope was sampled using maximizing the prediction gain. The paper deals with the a frequency with the time period of 41,66 gs yielding to analysis of the effect ofprediction range length on the 24 000 samples/s of the Rayleigh fade envelope, which prediction error of the radio communication channel was stored in the computer memory for further state. Results of the simulation in Matlab are applicable processing.in optimal radio channel adaptation methods.The simulation was set up as follows ( Fig. 1): the mobile station was moving at a speed of 211,8 km/h during 0,2 s, then its speed was decreased to 169,6 km/h Keywords until 0,4 s and from 0,4 s up to 0,6 s the speed was 40,5 km/h. Then the mobile station started to accelerate Kalman filter, Adaptive setting of the prediction up to 93,2 km/h until 0,8 s and from that time its speed range, 3G mobile communication network, grow up to 214,9 km/h. The total simulation time was Rayleigh fade envelope.1 second with 24 000 samples. This improbable scenario has been chosen to show the changes in fading envelope and the performance of proposed adaptation algorithm.
