sentence: Moreover , one can obtain that the computational complexity of the proposed STPAP algorithm is almost equal to that of the existing STPAP algorithm based on the criterion in [ 31 ] with the assumption that the calculation amount of T and V can be ignored.As depicted in Figure 12 and Figure 13 , it can be seen that the number of addition and multiplication that used in the proposed STPAP algorithm and the existing STPAP algorithm in [ 31 ] are always less than that of the existing STPAP algorithm based on the criterion in [ 30 ] when there are different tap number and element number .
