Comprehensive assessment of radio channels by information symbols of MIMO-OFDM signals by means of multivariate Kalman filter
Engineering Education # 10, October 2012
DOI: 10.7463/1012.0465244
 The authors propose an algorithm which estimates and corrects the MIMO-OFDM-channel with frequency-selective fading in phase noise on the basis of the multidimensional digital Kalman filter. The channel model is constructed in the form of autoregressive function based on the Jakes model. White frequency noise is considered as a model of phase impact. Research results of the algorithm show its high efficiency in fast fading. The authors performed parametrical adaptation of the proposed algorithms and formulated approaches to assessment and correction of channel parameters with account of the features and structure of the data packet technology 802.16e /m, E-UTRA release 9 (LTE-Advanced).
