The explosive growths of wireless devices (smart-phones, tablets, machines, sensors, etc.) and mobile data traffic are driving demand for wireless access far beyond the capabilities of the current generation of wireless networks. Future wireless networks (5G and beyond) are expected to dramatically increase data rate, network capacity and energy efficiency and lower the latency. To meet these expectations, significant technological innovations will be required.******Today, there is no single technology representing 5G networks and beyond. Instead, there are several promising candidate technologies, including in-band full-duplex (FD) radio, massive MIMO, millimeter-wave communications (mmWave), new multicarrier modulation, and relaying. The general consensus is that the integration of these candidate technologies will be required in future wireless networks. Among these emerging technologies, FD communication is very promising since it offers the potential to double the spectral efficiency relative to the conventional half-duplex systems by allowing a node to conduct simultaneous transmission and reception over the same frequency band. The concept of FD communication is not new but was long considered impractical given the very high level of self-interference that an FD device's transmitter causes to its own receiver. The renewed interests in FD are largely due to the fact that network providers have shrunk cell sizes to enable increased spatial reuse. Such architectural change towards shorter-range links permits reduced transmission power, thereby lessening the self-interference problem and making practical FD communications closer to reality.******The long-term objectives of the proposed research program are to use tools and insights from information theory, communications, signal processing and optimization to advance understanding and innovations in providing more efficient communication services over wireless networks. The research program will be advanced to such long-term objectives through the pursuit of several short-term objectives concerning the design and analysis of FD communications with new multicarrier waveforms, namely generalized frequency-division multiplexing (GFDM) and circular filter-bank multicarrier (C-FBMC). These multicarrier waveforms are being seriously considered as the air interface in 5G networks and to replace the orthogonal frequency-division multiplexing (OFDM) waveform widely used in 4G networks. This is because GFDM and C-FBMC can resolve the major limitations of OFDM in requiring strict synchronization and generating high out-of-band emission. The outcomes of the proposed research program, both in research innovations and HQP training, will continue to help Canada remain internationally competitive and influential in the rapidly growing wireless communication industry.

无线设备（智能手机，平板电脑，机器，传感器等）和移动数据流量的爆炸性增长使对无线访问的需求远远超出了当前一代无线网络的功能。未来的无线网络（5G及以后）有望大大提高数据速率，网络容量和能源效率，并降低延迟。为了满足这些期望，将需要大量的技术创新。******今天，没有一个代表5G网络及以后的单一技术。取而代之的是，有几种有前途的候选技术，包括频段全双工（FD）无线电，大型MIMO，毫米波通信（MMWave），新的多载波调制和继电器。一般共识是，将来的无线网络将需要这些候选技术的集成。在这些新兴技术中，FD通信非常有前途，因为它通过允许节点在同一频带上进行同时进行传输和接收，从而提供了相对于常规半双层系统的光谱效率的潜力。 FD通信的概念并不是什么新鲜事物，但鉴于FD设备的发射器会导致其自己的接收器，因此长期以来被认为是不切实际的。 FD中的新兴趣主要是由于网络提供商具有缩小细胞大小以实现增加空间再利用的事实。这种建筑变化向较短的链接链接允许降低传输功率，从而减少了自我干扰问题并使实用的FD通信更接近现实。****** ******拟议的研究计划的长期目标是使用信息理论，通信，信号处理和优化的工具和洞察力，以提高无线网络的理解和创新，从而超过无线网络。该研究计划将通过追求有关与新的多载波波形的设计和分析的几个短期目标，即通过新的多个多载波波形的设计和分析，即通用频率分割多路复用（GFDM）和圆形滤波器滤波器银行多载波（C-FBMC）。这些多载波波形被认真考虑为5G网络中的空气界面，并替换了4G网络中广泛使用的正交频段多路复用（OFDM）波形。这是因为GFDM和C-FBMC可以解决OFDM的主要局限性，以严格同步并产生较高的带外排放。在研究创新和HQP培训中，拟议的研究计划的结果将继续帮助加拿大在迅速发展的无线通信行业中保持国际竞争力和影响力。
