Reliable Information Transmission Techniques for Multi-Terminal Communication

该研究计划的重点是通过使用先进的编码，调制和信号处理技术来提高未来无线和光通信系统的数据传输速度。该计划的目标集中在通信和信号处理技术的设计和应用，可以更好地利用现有的和新兴的通信频谱。* 与传统的通信系统相反，在传统的通信系统中，数据以所谓的奈奎斯特速率传输，该速率等于可用通信信道带宽的两倍，本研究计划侧重于比奈奎斯特快的通信，其中数据以超过奈奎斯特速率的速率通过物理通信信道发送。比奈奎斯特快的传输方法具有显著提高通信速度的固有潜力，但是超过奈奎斯特速率限制导致非常严重的符号间干扰，直到最近才阻止这些通信系统的实际开发和利用。 * 特别地，当使用比奈奎斯特快的传输时，将对物理通信信道的多终端、多用户和连续时间结构进行建模。所获得的新信道模型将用于一对多（上行链路）、多对一（下行链路）和多对多（中继、协作和/或多天线）设置中的通信，这些设置尚未被其他人研究用于比奈奎斯特快的传输。将分析所获得的信道模型的信道容量和干扰结构，然后利用，以实现所获得的通信带宽利用率（频谱效率）和用户数据速率的数量级的改进。此外，级联差错控制码（例如，Turbo、低密度奇偶校验、Raptor和/或Polar）、用于比奈奎斯特传输更快的高级调制技术、迭代Turbo信号处理和多天线/端口技术将产生可以实际实现系统级改进的预期目标的系统架构。*所获得的研究成果和技术将导致更好的通信频谱利用率和更快的通信速度。这项工作及其应用将对加拿大的电信设备和基础设施制造商（例如，爱立信加拿大，华为，Ciena，黑莓），并将提供好处，电信服务提供商（例如，Bell Canada，Videotron，Rogers，Telus）。在整个拟议的研究计划中，研究生（5名博士和10名MEng水平）和10名研究型本科生将接受培训，获得通信系统，信号处理和编码技术的前沿知识和研究技能，使他们能够在工业和学术界获得未来的就业机会。

This proposed research program focuses on increasing data transmission speeds in future wireless and optical communication systems through the use of advanced coding, modulation and signal processing techniques. The program objectives focus on design and application of communication and signal processing techniques that can better utilize both the existing and emerging communication spectrum. ***As opposed to traditional communication systems, where data are transmitted at so called Nyquist rate which is equal to twice the available communication channel bandwidth, this research program focuses on Faster-than-Nyquist communication, where  data are sent over a physical communication channel at rates exceeding the Nyquist rate. The Faster-than-Nyquist transmission approach has an inherent potential to significantly increase the speed of communication, but exceeding the Nyquist rate limit leads to very severe inter-symbol interference that prevented practical development and utilization of these communication systems until very recently.  ***In particular, multi-terminal, multi-user and continuous-time structure of the physical communication channels will be modeled when Faster-than-Nyquist transmission is utilized. The obtained new channel models will be for communication in one-to-many (uplink), many-to-one (downlink) and many-to-many (relay, collaborative and/or multi-antenna) settings, which have not been studied for the Faster-than-Nyquist transmission by others. The obtained channel models will be  analyzed for their channel capacity and interference structure, then exploited in order to achieve order of magnitude improvements in obtained communication bandwidth utilization (spectral efficiency) and user data rates. Furthermore, design of concatenated error-control codes (e.g., turbo, low-density parity check, Raptor and/or polar), advanced modulation techniques for faster-than-Nyquist transmission, iterative turbo signal processing and multi-antenna/port technology will result in system architectures that can practically achieve envisioned goals of system level improvements.***The obtained research results and techniques will lead to better communication spectrum utilization and faster communication speeds. This work  and its applications will be of interest and benefit to telecommunication equipment and infrastructure manufacturers in Canada (e.g., Ericsson Canada, Huawei, Ciena, Blackberry) and will also provide benefits to telecom service providers (e.g., Bell Canada, Videotron, Rogers, Telus). Throughout the proposed research program, graduate students (5 PhD and 10 MEng level) and 10 research undergraduate students will be trained, acquiring cutting edge knowledge and research skills in communication systems,  signal processing and coding techniques that will enable them to obtain future employment in industry and academia.**
