Abstract :
A new cost function is proposed to recover signal projection in wavelet Space. It is shown that if an interpolation function exists in the wavelet subspace, then the recovery of signal is identical to the minimization of cost function, which projects the signal on the approximation space. At last, the simulation proves our conclusion.
