An Improved Sparsity Adaptive Matching Pursuit Algorithm and Its Application in Shock Wave Testing

Figure 1

The flow chart of the DCBSAMP Algorithm (flag1 is a flag bit for judging how many times the algorithm reaches the iteration stop condition: when flag1 = 0, the algorithm reaches the iteration stop condition for the first time; when flag1 = 1, the algorithm reaches the iteration stop condition for the second time).
