In this paper the performance of the Frequency Domain LMS adaptive filter is investigated, for the case when the Sliding Discrete Fourier Transform is utilized for the frequency domain data transformation. A statistical performance analysis in terms of the mean, and the mean squared error of the filter parameters is presented. The convergence speed of the algorithm is analyzed in terms of the eigenvalue spread of the input signal autocorrelation matrix. The theoretical analysis results are verified by computer simulations.
