面向绿色通信的自我修复射频电路关键技术研究

With the aggravation of the energy shortage and environment pollution, green communications becomes the core concept for the development of communication industry in china. The existing green communication technology focuses on the energy reduction, while this project concentrates on the improvement of reliability of system, and explores an approach to implement the self-healing radio frequency circuits, which will be capable of detecting and quickly responding to possible assaults. The technique can prolong the service life of hardware, and therefore achieves resource saving and emission reduction. In the preliminary study, we can find that the unique multiple-path topology of distributed amplification structure provides an effective mechanism to implement crash recovery. This project will investigate the basic element for self-healing property, explore the efficiency and accurate self-healing algorithm, design the corresponding broadband amplifier and active power divider, and summarize the design guideline and analysis methods for different self-healing components. During the project implementation, the important theoretical and technical issues for self-healing radio frequency circuits will be resolved, especially for the case of circuit failure caused by damaged transistors. The self-healing technique will be extended to different radio frequency components and system-level applications, driving the “green” evolution of wireless communications.

在能源日益短缺与环境污染日益加剧的今天，绿色通信成为我国通信业未来发展的核心理念。现有的绿色通信技术主要集中在降低能耗上，本项目从提高系统可靠性着手，探索实现自我修复(self-healing)射频电路的方法，旨在使电路在运行过程中能够及时检测并自动修复各种故障，有效延长器件的工作寿命,达到节源减排的目的。我们在前期研究中发现分布式放大结构独有的多路信号通道可为故障修复提供硬件机制。本项目将在此基础上研究具有自我修复功能的基本硬件单元，探索高效准确的自我修复算法，研制可自我修复的宽带放大器和有源功分器，并总结出一套可自我修复射频器件的通用设计与分析方法。.通过本项目的实施，解决可自我修复射频电路面临的一些主要理论和技术问题，特别是攻克晶体管损坏导致电路失效这一固有难题，实现自我修复技术在射频器件和系统级场景中的应用，推进无线通信系统的绿色演化。
