提出了Blackman窗插值算法，通过Ad Hoc算法得到信号模极大值，利用Blackman窗对信号模极大值点进行插值，得到信号的估计小波系数进而依此小波系数直接重构信号。仿真结果表明，该算法具备了模极大值直接重构算法的快捷性和交替投影法的精确性，提高了信噪比，降低了失真度。

The Blackman window interpolation algorithm is put forward, the signal modulus maxima are obtained by Ad Hoc algorithm, the signal estimated coefficients of wavelet can be obtained from the interpolation of Blackman window be-tween the modulus maxima points of signal and reconstruct signal by the signal estimated wavelet coefficients. The simu-lation results demonstrate that the novel algorithm with the fast speed of modulus maximum direct reconstruction algo-rithm and the accuracy of alternating projection algorithm, improves the SNR and reduces the distortion.
