Abstract

In practical systems, colored noise commonly imposes on the data delivered, since the ideal white noise can hardly be achieved. In order to suppress the noise, we propose a denoiser based on a fully convolutional denoising autoencoder (FCDAE) for more reliable information recovery. The smart FCDAE consists of a fully convolution-based encoder and decoder to learn the noise structure distribution in the received signals. Besides, the loss function is selected as a combination of mean square error (MSE) and normality test loss. The proposed denoiser can be further combined with decoders such as the low-density parity-check (LDPC) codes. The simulation results over channels with correlated noise demonstrate that the proposed FCDAE denoiser can effectively improve the signal-to-noise ratio (SNR) and bit error rate (BER) performance, thereby achieving superior reliability performance to benchmark systems.
