Wireless connectivity has advanced at a frenetic rate, building from station-to-station communication (thousands of connections), through station-to-people modalities (millions of connections), to the current people-to-people connectivity (billions of connections). Incredibly, the rise in connectivity needs has been met with relatively incremental advances in wireless communication, culminating in our current fourth generation (4G) technology. However, this technology will no longer suffice to meet increasing connectivity demands. In the next decade, trillions of devices will connect people-to-people, people-to-things and things-to-things turning familiar items into so-called smart objects with built-in sensing and networking capabilities, and propelling wireless connectivity to the tera-scale. Fifth-generation (5G) wireless technologies will require completely new wireless devices, communication infrastructure and networks to meet the unprecedented challenges, which include 100-1000 times higher system capacity, data throughput of up to gigabytes per second everywhere, latency down to 1 millisecond, and 10 times longer device battery life, while lowering cost and power consumption. Global research efforts have been focused on developing solutions for 5G network architecture, communication protocols, and signalling schemes, while investigations into the necessary underlying radio hardware have been limited. In addition, most of the existing 5G technology research is reliant on traditional assumptions about the radio hardware (e.g., antenna reciprocity, transmitter and receiver linearity, flat frequency response) that will be very difficult, if not impossible, to satisfy, given that 5G's air interface will extend to the millimeter wave (mm-wave) frequencies and will feature large-scale multi-antenna technologies. This underscores the need for low cost and energy efficient microwave and mm-wave massive multiple-input multiple-output (MIMO) and beamforming transceivers, particularly the transmitter (M4BTx). However, the development of M4BTx is predicated on finding new ways to strike a balance between linearity and efficiency trade-offs. Hence, the proposed research program will lead to novel theories and techniques that will culminate in streamlined and efficient engineering practices and methodologies capable of attaining high-performance radio hardware. A large number of HQP will be trained through this program. The intellectual property and demonstrators generated from this work will be of value and relevance to Canadian industry and will strengthen industrial and academic collaborations and partnerships. Together, these achievements will help Canada to maintain its global leadership in wireless technologies, and to productively contribute to the advancement of 5G on an international scale.

无线连通性以疯狂的速度提高了，从站到站的通信（数千个连接），到车站到人民的方式（数百万连接）到当前的人与人之间的连接（数十亿个连接） 。令人难以置信的是，无线通信的连通性需求的上升已得到相对增长的进步，最终达到了我们目前的第四代技术（4G）技术。但是，这项技术将不再足以满足不断增长的连接需求。在接下来的十年中，数万亿个设备将连接人与人之间的人，人与人之间的事物，将熟悉的物品变成具有内置感应和网络功能的所谓智能对象，并推动无线连接到TERA级。第五代（5G）无线技术将需要全新的无线设备，通信基础设施和网络来应对前所未有的挑战，其中包括更高的系统容量，数据吞吐量的100-1000倍，每秒多达千兆字节，延迟降至1毫秒至1毫秒，设备电池寿命更长的10倍，同时降低成本和功耗。 全球研究工作一直集中在为5G网络体系结构，通信协议和信号方案开发解决方案上，而对必要的基础无线电硬件的调查受到限制。此外，大多数现有的5G技术研究都依赖有关无线电硬件的传统假设（例如，天线互惠，发射器和接收器线性，平坦的频率响应）将非常困难，即使不是不可能，因此可以满足5G的满足感。空气界面将延伸到毫米波（MM波）频率，并具有大规模的多Antenna技术。这强调了低成本和节能微波炉和MM波的需求，大量的多输入多输出（MIMO）和波束成形收发器，尤其是发射器（M4BTX）。但是，M4BTX的发展是基于寻找新的方法来实现线性和效率权衡之间平衡的新方法。因此，拟议的研究计划将导致新颖的理论和技术，这些理论和技术将达到流线和高效的工程实践和能够获得高性能无线电硬件的方法。通过此计划将对大量HQP进行培训。这项工作产生的知识产权和示威者将对加拿大产业具有价值和相关性，并将加强工业和学术合作和伙伴关系。这些成就将共同有助于加拿大维持其在无线技术方面的全球领导力，并有效地在国际规模上提高5G。
