  • Machine Learning for Wireless Networks

    Next-generation wireless networks must support ultra-reliable, low-latency communication and intelligently manage a massive number of Internet of Things (IoT) devices in real-time, within a highly dynamic environment. This need for stringent communication quality-of-service (QoS) requirements as well as mobile edge and core intelligence can only be realized by integrating fundamental notions of artificial intelligence (AI) and machine learning across the wireless infrastructure and end-user devices. In this context, this paper provides a comprehensive tutorial that introduces the main concepts of machine learning, in general, and artificial neural networks (ANNs), in particular, and their potential applications in wireless communications. For this purpose, we present a comprehensive overview on a number of key types of neural networks that include feed-forward, recurrent, spiking, and deep neural networks. For each type of neural network, we present the basic architecture and training procedure, as well as the associated challenges and opportunities. Then, we provide an in-depth overview on the variety of wireless communication problems that can be addressed using ANNs, ranging from communication using unmanned aerial vehicles to virtual reality and edge caching.For each individual application, we present the main motivation for using ANNs along with the associated challenges while also providing a detailed example for a use case scenario and outlining future works that can be addressed using ANNs. In a nutshell, this article constitutes one of the first holistic tutorials on the development of machine learning techniques tailored to the needs of future wireless networks.

    Verilog HDL简明教程 硬件描述语言(Hardware Description Language,简称HDL)是硬件设计人员和电子设计 自动化(EDA)工具之间的界面。其主要目的是用来编写设计文件,建立电子系统行为级的 仿真模型。即利用计算机的巨大能力对用Verilog HDL或VHDL建模的复杂数字逻辑进行仿真, 然后再自动综合以生成符合要求且在电路结构上可以实现的数字逻辑网表(Netlist), 根据 网表和某种工艺的器件自动生成具体电路,然后生成该工艺条件下这种具体电路的延时模型。 仿真验证无误后用于制造ASIC芯片或写入EPLD和FPGA器件中。 自从Iverson于1962年提出HDL以来,许多高等学校、科研单位和大型计算机厂商都相继 推出了各自的HDL,但最终成为IEEE技术标准的仅有两个即Verilog HDL和VHDL
