Low Complexity Channel estimation with Neural Network Solutions

Overview

Interpolation-ResNet

Invited paper for WSA 2021, called 'Low Complexity Channel estimation with Neural Network Solutions'.

Low complexity residual convolutional neural network for channel estimation

Conpared with the ReEsNet from the repo Residual_CNN, it has slightly improved performance and the number of parameters is reduced by 82% (when pruning is not applied). I planed to release the code when I sorted out the files.
