[0027] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0028] The analysis of the existing series of matching pursuit methods shows that in each iteration, the inner product of each column of the sensing matrix Φ and the signal residual determined in the previous iteration needs to be calculated, that is, to calculate The product of the transposition of the sensing matrix and the signal residual r Φ T r, involves matrix operations; further, in order to calculate the signal residual, it is necessary to calculate an approximate solution of the reconstructed signal in each iteration. It can be seen that in the series of matching and tracking methods, each iteration involves matrix operations, and each iteration needs to calculate the approximate solution of the reconstructed signal. This part of the calculation process will cons...
