论文摘要
近年来,采用深度学习(DL)技术在通信系统中成为一种常见实践,证明了有希望的结果。本文提出了一个新的卷积神经网络(CNN)基于变异的自动编码器(VAE)通信系统。与AE(分布式潜在空间)和其他传统方法相比,基于VAE(连续的潜在空间)的通信系统赋予了系统性能前所未有的改进。我们已经在拟议的VAE中引入了可调节的高参数beta,也称为β-VAE,导致了极度分解的潜在空间表示。此外,采用了潜在空间的高维表示,例如4N维而不是2N,降低了块错误率(BLER)。所提出的系统可以在添加宽的高斯噪声(AWGN)和瑞利褪色通道下运行。基于CNN的VAE架构在发射器上执行编码和调制,而在接收器处进行解码和解调。最后,为了证明连续的潜在空间系统指定的VAE的性能优于其他系统,在正常和嘈杂的条件下,已经授予了支持相同的各种模拟结果。
In recent years, applying Deep Learning (DL) techniques emerged as a common practice in the communication system, demonstrating promising results. The present paper proposes a new Convolutional Neural Network (CNN) based Variational Autoencoder (VAE) communication system. The VAE (continuous latent space) based communication systems confer unprecedented improvement in the system performance compared to AE (distributed latent space) and other traditional methods. We have introduced an adjustable hyperparameter beta in the proposed VAE, which is also known as beta-VAE, resulting in extremely disentangled latent space representation. Furthermore, a higher-dimensional representation of latent space is employed, such as 4n dimension instead of 2n, reducing the Block Error Rate (BLER). The proposed system can operate under Additive Wide Gaussian Noise (AWGN) and Rayleigh fading channels. The CNN based VAE architecture performs the encoding and modulation at the transmitter, whereas decoding and demodulation at the receiver. Finally, to prove that a continuous latent space-based system designated VAE performs better than the other, various simulation results supporting the same has been conferred under normal and noisy conditions.
