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.

在这个研究项目中，我们将研究高级协作通信技术的设计和实现。具体地说，我们将研究以下三个主题：1)协作路由，2)全双工中继，3)非高斯信道下的协作通信。**协作路由考虑了物理层协作传输的可用性。我们将研究协作路由在不同类型的无线网络中的实现和采用。此外，与现有的关注能量最小化的工作不同，我们将考虑分组冲突概率和分组投递率。**在全双工中继中，中继器通过为中继器配备两个天线(一个用于接收，一个用于发送)，并采用自干扰抵消，可以同时接收和发送。我们将通过实验工作来分析在现实条件下全双工中继的可行性。此外，我们还将研究有效的干扰消除和信号检测技术的使用。**非高斯噪声在许多情况下都存在，例如在车载通信系统中(由于火花塞噪声)。对于具有非高斯噪声的协作系统，将寻求复杂度更低的接近最优的检测算法。此外，我们还将使用解析方法分析非高斯协作系统的性能。**将使用计算机仿真、解析方法和实验工作对所提出的算法进行分析。这项研究的结果对于深入了解协作通信系统及其性能是至关重要的。此外，研究结果还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应用。这带来了各种优势，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、更低的能源消耗(为绿色通信范式铺平道路)，以及更便宜的无线通信服务。这不仅适用于蜂窝无线通信，也适用于其他无线通信系统，如无线传感器网络和车载自组织网络。**此外，该研究计划将能够培养7名研究生和至少18名本科生。所有学生将在无线通信和相关领域(例如，网络和数字信号处理)的高级主题方面建立坚实的基础。此外，学生将使用高级数学和分析技术(例如，分析最优化和随机过程)。此外，学生将使用模拟工具(例如，NS2/NS3、OMnet++和QualNet)。因此，这项研究计划将为学生提供必要和重要的理论和实践技能，这些技能是他们在行业或学术界取得成功所必需的。**总而言之，这项研究计划旨在推动无线通信领域的发展。随着430亿美元的总销售额和超过26万加拿大人在无线通信领域工作(根据Ovum Europe Ltd.：无线电信产业给加拿大经济带来的好处，2012年6月的报告)，无线通信代表着加拿大经济发展中最具战略意义的行业之一。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，我们将帮助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。
