论文摘要
下一代无线系统旨在满足各种应用程序要求,但从根本上依赖点对点传输质量。本文介绍了与最新的AI启用无线实现的一致性,介绍了自主性无线电6G-AUTOR,它利用了新颖的算法 - 硬件分离平台,传输软件(TX)和接收(RX)操作以及RF前端的自动重新配置,以支持链接和韧性。作为一种全面的收发器解决方案,我们的设计涵盖了几种ML驱动的模型,每个模型都增强了TX或RX的特定方面,从而在未来无线系统的严格限制下导致了强大的收发器操作。通过Deep Q-Networks开发了一个数据驱动的无线电管理模块,以支持TX资源块(RB)和主动多代理访问的快速重新配置。同样,采用了重新启发的快速构造解决方案,以在同一RB上与多个接收器进行牢固的通信,该解决方案在实现无细胞基础架构时具有潜在的应用。作为接收器,系统配备了超宽带频谱识别能力。除此之外,涉及复杂的相关提取的基本工具 - 自动调制分类(AMC),然后是基于卷积的神经网络(CNN)分类,并添加了基于学习的LDPC解码器,以提高接收质量和无线电性能。单个算法的仿真表明,在适当的训练下,每个相应的无线电函数都超出了或与基准溶液以PAR进行的。
Next-generation wireless systems aim at fulfilling diverse application requirements but fundamentally rely on point-to-point transmission qualities. Aligning with recent AI-enabled wireless implementations, this paper introduces autonomic radios, 6G-AUTOR, that leverage novel algorithm-hardware separation platforms, softwarization of transmission (TX) and reception (RX) operations, and automatic reconfiguration of RF frontends, to support link performance and resilience. As a comprehensive transceiver solution, our design encompasses several ML-driven models, each enhancing a specific aspect of either TX or RX, leading to robust transceiver operation under tight constraints of future wireless systems. A data-driven radio management module was developed via deep Q-networks to support fast-reconfiguration of TX resource blocks (RB) and proactive multi-agent access. Also, a ResNet-inspired fast-beamforming solution was employed to enable robust communication to multiple receivers over the same RB, which has potential applications in realisation of cell-free infrastructures. As a receiver the system was equipped with a capability of ultra-broadband spectrum recognition. Apart from this, a fundamental tool - automatic modulation classification (AMC) which involves a complex correntropy extraction, followed by a convolutional neural network (CNN)-based classification, and a deep learning-based LDPC decoder were added to improve the reception quality and radio performance. Simulations of individual algorithms demonstrate that under appropriate training, each of the corresponding radio functions have either outperformed or have performed on-par with the benchmark solutions.
