🔧 Environment Setup

To create a new conda environment, execute the following command:

conda create --name invsems python==3.8

⚡Activate Environment

Activate the created environment with:

conda activate invsems

📦 Install Required Packages

The following packages can be installed using pip:

pip install numpy
pip install scipy
pip install scikit-image
pip install torch
pip install torchvision
pip install opencv-python
pip install tqdm

Please pay attention to the torch version, according to your CUDA version. Refer to here.

🏃‍♀️ Run the Program

Set the created env as the runing env:

Run main.py to start the program.

🔍 Check the results

In this demo, we consider the encoding and decoing of wireless signal amplitude information as:

With the decoding process going, the results will be recorded:

After 2 decoding steps, the result is not good:

After 16 decoding steps, the result is quite good:
