Algorithm 1

Proposed OTQWT algorithm.
(1)Initialize and
(2)Get using equation (13)
(3)Decompose the signal by OTQWT using and
(4)Obtain the approximate signal using inverse OTQWT with and N (number of samples)
(5)Find the mean square error, using equation (16)
(6)While (min(MSE)) do
(7)If (MSE = = min) then
(8)Optimum and
(9)Else
(10)Iterate with different and
(11)End if
(12)End while
(13)Choose the values of and for minimum MSE
(14)Find from and for each signal
(15)Repeat steps 1–14 for each PQD signal
(16)Find the optimum decomposition level from using equation (18)
(17)Decompose the PQD signal by OTQWT using and
