This article covers analysis of channel estimation problem combined with compensation of linear distortions in frequency responses of radio paths of a MIMO system. First part of the paper covers an origin of the problem and its effects on various aspects of MIMO system, analysis of existing papers is also included. Main part of the paper consists of a mathematical description of the problem and proposed solution to it. Results of the work include a mathematical formulation of channel estimation algorithm, combined with a compensation of linear distortions of radio paths frequency responses. Improvement ratios can be observed by comparison of spectral efficiency of the system with and without linear distortions in addition to a quality of such estimation.
