Fourth-generation (4G) wireless communications are expected to deliver very high transmission rates to or from mobile terminals over different multi-carrier and multi-antenna air-interfaces in a seamless and versatile fashion, no matter what the surrounding environment, link conditions and network topologies are. This stringent requirement calls for developing new "cognitive" transceivers that swiftly and optimally adapt to variable operating conditions such as changes in multi-carrier and/or multi-antenna air-interface configuration, mobility, traffic location and/or load, propagation characteristics, and/or topology in mobile ad hoc networks (MANETs) in particular. This research project is directed at developing enhanced signal processing techniques as powerful tools for the efficient design of such new "cognitive" transceivers. These transceivers would not only provide the self-adaptation capability required by future wireless technologies to optimally operate in variable transmission conditions, but will also offer transparent migration between different radio interfaces and network topologies, all available form then on at low hardware cost on a unique wireless terminal. They would bring extremely efficient solutions to the tremendous challenges posed by future deployment of 4G such as designing multi-mode terminals and allowing transceiver software radio reconfiguration by software downloads over the air. From this perspective, they could have a major impact on future deployment of 4G by simplifying both the design of the terminals and the discovery/selection of the wireless system among the many that will be offered simultaneously to the user.

期望第四代（4G）无线通信以无缝和通用的方式通过不同的多载波和多天线空中接口向或从移动的终端递送非常高的传输速率，而不管周围环境、链路条件和网络拓扑是什么。这种严格的要求要求开发新的“认知”收发器，其快速且最佳地适应于可变的操作条件，例如多载波和/或多天线空中接口配置、移动性、业务位置和/或负载、传播特性和/或特别是移动的自组织网络（MANET）中的拓扑的变化。本研究项目旨在开发增强的信号处理技术，作为有效设计这种新的“认知”收发器的强大工具。这些收发信机将不仅提供未来无线技术所需的自适应能力，以在可变传输条件下最佳地操作，而且还将提供不同无线电接口和网络拓扑之间的透明迁移，所有可用的形式都将以低硬件成本在唯一的无线终端上实现。它们将为未来部署4G带来的巨大挑战带来极其有效的解决方案，例如设计多模终端，并允许通过空中软件下载重新配置收发器软件无线电。从这个角度来看，它们可以通过简化终端的设计和在将同时提供给用户的许多无线系统中发现/选择无线系统来对4G的未来部署产生重大影响。
