基于基带-射频联合优化的下一代无线通信系统关键技术研究

Joint baseband (BB) and radio frequency (RF), as a promising low power technology, has been followed by academia and industry. Due to the early stage of joint BB-RF research, the innovation points are dispersed around with limited supporting of fundamental theories. In this project, we plan to systematically investigate the characteristics of RF components and changing mechanism for the next generation communication systems, and build a unified analytical power model for joint BB-RF optimization. On top of that, we will research on the RF tunable parameters and control mechanism in order to build the control theory, and investigate the corresponding theory related to BB-RF shut-off. Guided by the models and theories, the project will focus on the matching relation and joint optimization mechanisms between the key technology in the BB and the tunable RF links through the theoretical and prototype research, and pay special attention to dynamic adjustment of RF key parameters using BB processing information and improve the shut-off probability through optimized design. We will provide suggestions on the practical joint BB-RF optimization technologies and their combinations, which may lay a solid foundation for the energy efficient implementation of the next generation communication systems.

基带-射频的联合优化方向作为具有较大潜力的低功耗技术，已初步被学术界和工业界关注。但现有基带-射频联合优化的研究尚处于起步阶段，技术创新点较为分散，同时也缺乏基础理论的支撑。本项目拟通过系统地研究下一代通信系统中射频链路相关器件的特性及功耗变化机理，建立一套基带-射频功耗联合优化分析模型，开展射频可调参数的优化与控制研究；建立射频可调参数与基带控制理论，以及基带射频关断的相关理论。在这些基础模型与理论的指引下，本项目将通过理论研究与实验平台相结合的方式，摸索基带-射频联合优化机理，着重考虑利用基带处理部分的信息进行动态调整射频关键参数，以及通过优化设计增大各子系统的关断几率，提出可行的基带-射频联合优化技术或技术组合建议，为下一代无线通信系统实现高能效奠定基础。
