Abstract
This paper proposes a deep learning-based error correction coding for AWGN channels under the constraint of one-bit quantization in receivers. An autoencoder is designed and integrated with a turbo code that acts as an implicit regularization. This implicit regularizer facilitates approaching the Shannon bound for the one-bit quantized AWGN channels even if the autoencoder is trained suboptimally, since one-bit quantization stymies ideal training. Our empirical results show that the proposed coding scheme gives better results at finite block lengths than conventional turbo codes even for QPSK modulation, which can achieve the Shannon bound at infinite block length despite one-bit quantization. Furthermore, the proposed coding method makes one- bit quantization operational even for 16-QAM, which is unprecedented.
