Deep JSCC

This implements training of deep JSCC models for wireless image transmission as described in the paper Deep Joint Source-Channel Coding for Wireless Image Transmission by Pytorch. And there has been a Tensorflow and keras implementations .

This is my first time to use PyTorch and git to reproduce a paper, so there may be some mistakes. If you find any, please let me know. Thanks!

Architecture

Demo

Installation

conda or other virtual environment is recommended.

git clone https://github.com/chunbaobao/Deep-JSCC-PyTorch.git
pip install requirements.txt

Usage

Training Model

Run(example presented in paper)

cd ./Deep-JSCC-PyTorch

python train.py --lr 10e-4 --epochs 100 --batch_size 32 --channel 'AWGN' --saved ./saved --snr_list 1 4 7 13 19 --ratio_list 1/6 1/12 --dataset imagenet

or

python train.py --lr 10e-3 --epochs 100 --batch_size 512 --channel 'AWGN' --saved ./saved --dataset cifar10 --num_workers 4 --parallel True
