针对基带平台中的可重配置RF前端和异构多处理器SoC，提出了SDR的能量可缩放架构和电路。性能/能量管理器动态地利用能量可伸缩性以及应用需求和传播环境中的动态性，实现低功率操作。对于发射机，能量可扩展性被转化为高达40%的平均系统级能效改进。
Energy scalable architectures and circuits for SDRs are proposed, for both a reconfigurable RF front-end and a heterogeneous multiprocessor SoC in a baseband platform. A performance/energy manager dynamically exploits the energy scalability and the dynamics in application requirements and propagation environment, realizing low-power operation. For the transmitter, the energy-scalability is translated to an average system-level energy-efficiency improvement of up to 40%.
