Analysis of the performance results of the MARD-FFCI algorithm and the components, (a) The relationship between the estimation errors and SNR. The estimation errors are for different rough estimation methods combined with fine estimation methods and for the proposed modified algorithm, when a residual error factor is 0.45.(b) The relationship between estimation errors versus residual errors for different coarse estimation methods combined with fine estimation and for the proposed modified algorithm when SNR is 10 dB
