inverse wavelet packet transform #615

Closed apznv closed 9 months ago

Hi everyone, I am working on wavelet transform OFDM. For that, I want to do an Inverse wavelet packet transform of the data at the transmitter. However, IWPT depends on DWPT in matlab. is there any option to do IDWPT without doing dwpt in python. please help APZnv

You're going to have to be a little more specific about what your actual problem is. Are you talking about the inverse for wavelet packet transforms (i.e. the reconstruct method on one of the classes in https://pywavelets.readthedocs.io/en/latest/ref/wavelet-packets.html)? Please provide an actual code example if you can.

Hi rgommers, I am trying to model the OFDM system using Wavelet Transform. At the transmitter, I have to use inverse wavelet packet transform of the modulated data which is complex in nature. On the receiver side, I will use DWPT. I tried to generate the code using Matlab. But it is not working. In Matlab to generate IDWPT, we need an index vector that I don't have. reconstruction and decomposition work on the tree structure. SO confused,,,,, Thank you very much in advance, Regards apznv

I'm sorry, we (the maintainers) have extremely limited bandwidth to work on this package, and can't answer questions like these.
