Abstract

This paper presents a proficient way-out to cutback channel estimation complexity of multiple antenna wireless system using orthogonal matrix triangularization to eliminate matrix inversion that incurs higher complexity. Complexity evaluation of the proposed approach is validated through MATLAB simulations in terms of mathematical operations, which shows that the method noticeably outperforms training based least squares (LS) estimation at a lower complexity and represents a good solution of channel estimation.
