Green Multi-Antenna and MIMO Radio Transmitters

未来的通信网络需要比现在更加无处不在、更加灵活。它们将需要在多模式多标准通信环境中支持更大的移动性需求和更高的数据吞吐量。第五代（5G）无线技术计划于2020年初部署，预计将确保向后兼容性，并提供比目前部署的3G+和4G技术快100倍的数据传输速度的移动连接。功率效率和并行多标准可操作性将成为5G通信系统部署和可持续性的主要挑战。为了保持盈利能力，网络运营商将不得不为数十亿台设备提供100-1000倍的容量增长，同时实现将能耗和运营成本保持在当前水平的艰巨任务。一个典型的无线网络的总能耗中，无线电接口要占60%以上。因此，要实现5G服务，无线行业必须满足三个主要里程碑：(i)宽带和多频段能力；ii)节能传输，iii)多天线（MA）和多输入多输出（MIMO）收发器的设计。******根据申请人的研究愿景，无线传输系统的下一个进化步骤是通过在不同的无线电接口上重复使用频率来提高其功率和频谱效率，这些无线电接口配备了具有波束形成能力的多个发射天线。这个特性将允许动态改变发射机辐射的光束的功率、数量和方向。这种相控阵发射机将允许在功率、频率和时间方面动态和有效地共享可用资源，从而产生更大的容量、更好的灵敏度、选择性、抗干扰性以及更低的功耗。预期的方法是基于四个研究重点和方向：1)研究

Future communication networks will need to be more ubiquitous and agile than they are today. They will be required to support larger demands for mobility and higher data throughput within the environment of multi-mode multi-standard communications. Fifth Generation (5G) wireless technology is scheduled to be deployed in early 2020 and is expected to ensure backward compatibility and offer mobile connectivity with up to 100 times faster data transmission compared to currently deployed 3G+ and 4G technologies. Power efficiency and concurrent multi-standard operability will be the major challenges for the deployment and sustainability of 5G communication systems. To maintain profitability, network operators will have to provide a 100-1000 fold capacity increase to billions of devices, while achieving the difficult task of keeping energy consumption and operating costs at today's rates. Radio interface is responsible for more than 60% of the entire energy consumption of a typical wireless network. Therefore, to enable 5G services, the wireless industry will have to meet three main milestones: (i) wideband and multi-band capabilities; ii) power-efficient transmission, and iii) Design of multi-antenna (MA) and multi-input-multi-output (MIMO) transceivers.******According to the applicant's research vision, the next evolutionary step for wireless transmission systems is the improvement of their power and spectrum efficiency through frequency reuse across different radio interfaces that are equipped with multiple transmitting antennas with beamforming capabilities. This feature will allow dynamic changes to the power, number and direction of beams radiated by the transmitter. Such phased-array transmitters will allow the available resources - in terms of power, frequency and time - to be shared dynamically and efficiently, yielding more capacity, better sensitivity, selectivity, interference rejection, as well as lower power consumption. The methodology anticipated is based on four research thrusts and directions: i) stud
