摘要：

This paper describes the procedure to reduce an estimation bias of interpolated DFT and single-model sine-fit algorithms. Estimation bias reduction of more than an order of magnitude is attainable. The procedure does not modify the estimation algorithm itself and additional knowledge of the measurement system or additional sampled points are not required.
