چکیده :

We propose a novel joint equalizer and decoder system based on deep neural networks for linear time invariant multipath channels. We use polar codes as the channel code and train two neural networks to perform blind joint equalization and decoding without requiring channel state information or encoder parameters. The first deep neural network recovers the signal from channel distortion, and the second deep neural network decodes the polar code. We demonstrate the superior performance of our system over both conventional and deep convolutional neural network methods, especially under large channel estimation errors.
