摘要：
In this article, we present an explicit comparative analysis of the two low-complexity channel estimation techniques, which can be used in the pilot-assisted orthogonal frequency division multiplexing (OFDM) systems, - linear minimum mean squared error (LMMSE) and least squares (LS) criteria based. Numerical results are preceded by derivation of the optimum design form to yield both robustness and minimum possible computational complexity for the given class of algorithms. The work also investigates the effect of quantity and power of pilot subcarriers on estimation accuracy and BER performance.
