The LICENSE file states that the code is covered by the GPL3 license, but the LICENSE field in startup.py states that it is covered by a BSD 3-clause license. Which of these is correct?

Hello dear author, I modified the code according to your thoughts, but there was a problem with LDPC demodulation, his FEC did not work, I would like to ask if you can help me. Thank you so much!

Any plans for writing a documentation page or tutorial?

we would like to integrate with gdsfactory as a plugin as well

Hi, @edsonportosilva

I'm testing the basic_OOK codes shown in the ./examples, and the figures seem like:

Such results, unlike the preview in basic_OOK_transmission notebook, show a different pulse shaping method leading to abnormal spectrum.

With no revision of original codes, I guess it comes from an alternative PulseShape in the up-to-date version. May I know some tips to solve this? Thanks.

Dear Sir,
I encountered with some errors when runing examples 'test_WDM_transmission'. I tried to fix it, but failed. The main problems is in the function named equaliztion.coreAdaptEq. Here are the errrors during simulation:

1. It seems that the @njit dose not work on my PC.
   
2. In order to fix this, I delelte @njit, then there comes other errors.
   
   In order to fix this, I use Hiter[:, :, 0] = H to replace Hiter[:, :, 1] = H
3. Another index error comes.
   
   Can you help me figure out this bug? Thanks a lot.

Hello author, I would like to ask if the fec in your code only supports error correction of AWGN channel, and cannot correct error for WDM fiber channel

Dear sir:
I have tried your demo: "test_WDM_amp_transmission" in colab, but when I modified the distance to 800 km， it didn't work as shown in the following figure. I wonder if you could help me figure it out， thanks a lot for your help!

1. Rolloff cannot be zero in this repo.Error while rolloff is setted to zero in function rcFilterTaps() or rrcFilterTaps.
2. Upsample factor cannot be a decimal such as 1.2. 1.5 these are often used in practice
3. In this repository, DAC, the zero-order hold, and the quantization stages of DAC have not been taken into account. These elements can have an impact on the spectrum and are also crucial in practical simulations.
