Wireless communication technologies are at a pivotal point in their development as they move from supporting person-to-person voice communications to enabling person-to-person and machine-to-machine high rate data communications. As a result, the future will see a proliferation of wireless networks of varying architectures that support a multitude of services in a wide range of operating environments. This will be a particularly challenging environment for wireless devices to operate in. The radio spectrum will be flooded with transmissions that each device will have to sift in order to isolate the data intended for it, under strict power and complexity constraints imposed by the small size and low cost of wireless devices. The goal of the proposed research program is to support wireless communications in challenging environments through advances in physical layer design. More specifically, our objective is to develop a framework for the design, analysis and implementation of adaptive receiver algorithms that: 1. Addresses explicitly the fact that realistic wireless environments are non-stationary due to rapid changes in their physical characteristics and user population and, therefore, severely limit the amount of data available for receiver adaptation. 2. Permits low-complexity implementations that satisfy the strict size and power-consumption limitations of mobile devices.

无线通信技术正处于其发展的关键时刻，因为它们从支持人与人的语音通信转变为支持人与人和机器对机器的高速数据通信。因此，未来将看到各种架构的无线网络的激增，这些无线网络在广泛的操作环境中支持多种服务。对于无线设备来说，这将是一个特别具有挑战性的环境。无线电频谱将充斥着传输，每个设备都必须筛选这些传输，以便在无线设备的小尺寸和低成本施加的严格功率和复杂性限制下，分离出打算发送给它的数据。 拟议的研究计划的目标是通过物理层设计的进步来支持具有挑战性的环境中的无线通信。更具体地说，我们的目标是开发一个框架，用于设计、分析和实施自适应接收器算法，该算法： 1.明确解决了现实无线环境由于其物理特性和用户数量的快速变化而是非静态的这一事实，因此严重限制了可用于接收器适配的数据量。 2.允许低复杂度的实现，满足移动设备的严格尺寸和功耗限制。
