In this research program, we will investigate the design and implementation of advanced cooperative communication techniques. Specifically, we will investigate the following three topics: 1) Cooperative Routing, 2) Full-duplex Relaying, and 3) Cooperative Communication with Non-Gaussian Channels. Cooperative routing takes into consideration the availability of cooperative transmission at the physical layer. We will investigate the implementation and adoption of cooperative routing in different types of wireless networks. Furthermore, and unlike existing work that focuses on energy minimization, we will take into consideration the packet collision probability and packet delivery ratio. In full-duplex relaying, the relay can simultaneously receive and transmit by equipping the relay with two antennas (one for reception and one for transmission), and using self-interference cancelation. We will use experimental work to analyze the feasibility of full-duplex relaying under realistic conditions. Moreover, we will investigate the use of efficient interference cancelation and signal detection techniques. Non-Gaussian noise exists in many cases, such as in vehicular communication systems (due to the spark plug noise). Reduced-complexity near optimal detection algorithms will be sought for cooperative systems with non-Gaussian noise. In addition, we will analyze the performance of non-Gaussian cooperative systems using analytical methods. The proposed algorithms will be analyzed using computer simulation, analytical methods and experimental work. Results from this research are crucial for gaining deeper insight into cooperative communication systems and their performance. Also, the results can be utilized to enhance the performance of cooperative communication systems and facilitate their adoption in existing and future wireless systems. This leads to various advantages, such as the faster data rates, better service quality, more reliable wireless links, better utilization of the scarce radio spectrum, less energy consumption (paving the way to the Green Communication paradigm), and less costly wireless communication services. This does not apply to the cellular wireless communication only, but it also applies to other wireless communication systems, such as wireless sensor networks and vehicular ad-hoc networks. In addition, this research program will enable the training of seven graduate students and at least eighteen undergraduate students. All students will build a strong background in advanced topics in wireless communications and related areas (e.g., networking and digital signal processing). Moreover, the students will use advanced mathematical and analytical techniques (e.g., analytical optimization, and stochastic processes). Furthermore, the students will use simulation tools (e.g., NS2/NS3, Omnet++, and Qualnet). Therefore, this research program will provide students with essential and important theoretical and practical skills, required for their success in careers either in industry or academia. In conclusion, this research program aims to advance the field of wireless communication. With the total generation of $43 billion and more than 260,000 Canadians working in the wireless communication sector (according to the report of Ovum Europe Ltd.: The Benefit to the Canadian Economy from the Wireless Telecommunications Industries, June 2012), wireless communication represents one of the most strategic industries in Canada’s economic development. By improving the design and performance of new algorithms and protocols proposed in this research program, we will help in fuelling new innovative wireless technologies and services as well as preparing a new generation of students and highly-qualified personnel.

在本研究计划中，我们将研究先进的合作通信技术的设计和实现。具体来说，我们将研究以下三个主题：1）合作路由，2）全双工中继，和3）与非高斯信道的合作通信。协作路由考虑了物理层协作传输的可用性。我们将研究合作路由在不同类型的无线网络中的实现和采用。此外，与现有的工作，侧重于能源最小化，我们将考虑到数据包的碰撞概率和数据包的交付率。在全双工中继中，中继可以通过为中继装备两个天线（一个用于接收，一个用于发送）并使用自干扰消除来同时接收和发送。我们将使用实验工作来分析全双工中继在现实条件下的可行性。此外，我们将研究使用有效的干扰消除和信号检测技术。非高斯噪声存在于许多情况下，例如在车辆通信系统中（由于火花塞噪声）。降低复杂度的近最佳检测算法将寻求非高斯噪声的合作系统。此外，我们将使用解析方法分析非高斯合作系统的性能。所提出的算法将使用计算机模拟，分析方法和实验工作进行分析。从这项研究的结果是至关重要的，以获得更深入的了解合作通信系统及其性能。此外，研究结果可用于提高协作通信系统的性能，并促进其在现有和未来的无线系统中的采用。这导致各种优点，例如更快的数据速率、更好的服务质量、更可靠的无线链路、更好地利用稀缺的无线电频谱、更少的能量消耗（为绿色通信范例铺平道路）以及更低成本的无线通信服务。这不仅适用于蜂窝无线通信，而且也适用于其他无线通信系统，例如无线传感器网络和车载自组织网络。此外，这项研究计划将使七名研究生和至少十八名本科生的培训。所有学生都将在无线通信和相关领域的高级主题（例如，网络和数字信号处理）。此外，学生将使用先进的数学和分析技术（例如，分析优化和随机过程）。此外，学生将使用模拟工具（例如，NS 2/NS 3、Omnet++和Qualnet）。因此，该研究计划将为学生提供必要和重要的理论和实践技能，这些技能是他们在工业或学术界取得成功所必需的。总之，本研究计划旨在推动无线通信领域的发展。总发电量为430亿加元，超过26万加拿大人在无线通信部门工作（根据Ovum Europe Ltd的报告：无线通信产业对加拿大经济的好处》，2012年6月），无线通信代表了加拿大经济发展中最具战略意义的产业之一。通过改进本研究计划中提出的新算法和协议的设计和性能，我们将有助于推动新的创新无线技术和服务，并为新一代学生和高素质人才做好准备。
