The advent of wireless communications, whether terrestrial or satellite-based, has had profound economic andsocial impacts in Canada and throughout the world. Wireless services, (Cell Phones, WiFi, GPS, Bluetooth,Satellite Communication, Broadcasting, etc.) have become indispensable parts of any country's infrastructure.However, the accelerated pace of progress in this field has led to the proliferation of services and applications.This heterogeneous mix of applications, networks and standards is reminiscent of computer networks beforethe advent of the Internet. If the Internet experience is any indication, there are substantial gains to be realizedby consolidation and harmonization of the various wireless services. Such developments require, among otherthings, a new approach to wireless systems with new enabling technologies. Such approach and enabling tech-nologies are the subject of intense R&D efforts for future-generation wireless systems. The proposed researchprogram aims at developing the methodologies, architectures, designs and components that will be suitablefor future generation radio communication and radio navigation systems. The approach will be systemic innature but detailed in execution from devices to systems. At the device level, we will work on emerging Gal-lium Nitride transistors to realize more efficient transmitters. At the circuit level, we will work on developingnew circuits that can be embedded in analog transceivers to measure their performance. We will also work onnew miniaturized circuits that duplex transmit and receive frequencies more efficiently. We will further de-velop frequency-agile circuits that can be used to tune a given transceiver's frequency to the desired service. Put together, these devices/circuits will be used to produce novel transceiver electronics useful for radio communi-cation and/or navigation. When this circuitry is coupled to flexible digital platforms and multiple antenna sys-tems, their combined power can be fully exploited by networks and end user applications. This program will serve to train many undergraduate and graduate students, post-doctoral fellows and technicians. When possible, valorization of research results, through patenting, licensing or spin-off companies, will be pursued diligently.

无论是地面还是卫星无线通信的出现，都对加拿大和全世界产生了深远的经济和社会影响。无线服务，（手机，WiFi，GPS，蓝牙，卫星通信，广播等）已成为任何国家基础设施不可或缺的一部分。然而，这一领域的加速发展导致了服务和应用的激增。这种应用、网络和标准的异质混合使人想起互联网出现之前的计算机网络。如果互联网的经验是任何迹象，有大量的收益将实现合并和协调的各种无线服务。这些发展尤其需要一种具有新的使能技术的无线系统的新方法。这种方法和使能技术是下一代无线系统的密集研发工作的主题。拟议的研究计划旨在开发适合下一代无线电通信和无线电导航系统的方法，架构，设计和组件。该方法本质上是系统性的，但从设备到系统的执行细节。在器件层面，我们将致力于新兴的氮化镓晶体管，以实现更高效的发射机。在电路层面，我们将致力于开发可嵌入模拟收发器的新电路，以测量其性能。我们还将致力于新的小型化电路，双工发送和接收频率更有效。我们将进一步开发频率捷变电路，可用于调谐一个给定的收发器的频率所需的服务。这些器件/电路将用于生产新型收发器电子产品，用于无线电通信和/或导航。当该电路耦合到灵活的数字平台和多天线系统时，它们的组合功率可以被网络和最终用户应用充分利用。该计划将培养许多本科生和研究生，博士后研究员和技术人员。在可能的情况下，将通过专利、许可证或分拆公司，努力实现研究成果的价值。
