LDBP: Learned Digital Backpropagation

Getting Started

The code is based on TensorFlow 1.13.1 and may not work properly with other (older or newer) versions. It is recommended to create a dedicated conda environment using the YAML file in the folder conda as follows:

(base)~$ conda env create -f ldbp_env.yml
(base)~$ conda activate ldbp_env

Afterwards, it should be possible to run the provided jobscripts in the folder ldbp. For example:

(ldbp_env)~$ ./jobscript_isit

To train for different scenarios, most of the parameters and training options are set in a configuration file located in the folder config.
