Simulink simulation of wavelet decomposition and synthesis

The method of using 5-3 lifting wavelet

Wavelet decomposition

Data splitting

Update

Data output Enable circuit

Circuit a total of two input three output, in1 is the data input, in2 is the input data valid signal, OUT1 is the updated low-frequency signal, OUT2 is the high-frequency signal of the prediction, OUT3 is the output effective signal.

The circuit needs to consider the data boundary extension, I direct extension to 0, simple. There are other extension methods such as symmetric continuation and periodic continuation, did not make, just a layer of decomposition and synthesis of the circuit to build up, extension of the method is to extend the input data instead of using the circuit extension, saw someone else with electricity Lu Yanta, did not get.

The above is the decomposition circuit, the synthesis is not affixed, similar, put these things posted here, later if found wrong timely correction, beginners, inevitably make mistakes, if you see that there is a mistake can give me to point out, first thank you.
