摘要

认知无线电的频谱数据挖掘和敏捷空中接口要求是软件定义无线电(SDR)实现的要求。在任何频段检测和/或生成几乎任何类型波形的需求将这种SDR的规格推向了极限。这使得具有成本效益和节能的实施非常具有挑战性。作为迈向有效嵌入式认知无线电的第一步，我们提出了基于自顶向下方法的可扩展SDR平台的设计，该平台可实现频谱环境感知和响应传输。硬件成本和能源效率受到机会分配和积极的电源管理的竞争，导致10mw范围的待机功率和100mw范围的有功功率

A Scalable Baseband Platform for Energy-Efficient Reactive Software-Defined-Radio

The spectrum data-mining and agile air interface requirements of cognitive radios claim for software-defined-radio (SDR) implementations. The need to detect and/or generate virtually any kind of waveform in any band pushes the specification of such SDR to the limit. This makes cost-effective and energy-efficient implementation very challenging. As a first step toward effective embedded cognitive radio, we present the design, based on a top-down methodology, of a scalable SDR platform that enables spectrum environment awareness and reactive transmission. Hardware cost and energy-efficiency are contended by opportunistic partitioning and aggressive power management leading to 10 mW-range standby power and 100 mW-range active power
