Mobile Radio Link Adaptation by Radio Channel State Prediction

摘要

Applying the channel state prediction in 3G mobile communication networks [1, 2] allows securing a maximum spectral efficiency of the channel under the required error rate. The paper deals with the selection analysis of the optimum sampling period of the radio channel signal envelope [3] and prediction interval adaptation using Kalman filter to achieve minimum channel state prediction error. Results of radio channel state prediction simulations performed in Matlab are applicable in optimization of adaptation parameters of a real communication system [4].
