定了电台在战场的可运作时间。因此，数字平台的硬件设计和软件设计都必须把电台的大小
、重量和电源（SWAP）的设计作为首要的考虑事项。从动态时钟调整、电源供应调整、操作
模式、工作周期影响、静态和动态电源对比、硬件电源的小型化考虑以及可编程逻辑和ASIC
的设计对比等多方面进行了研究,为构建灵活的软件无线电平台体系结构提供了参考。 |

| Abstract: |
| For battery powered manpack and handhold radios, average power consumption of th
e radio dictates the operational life of the radio in battlefield operation. Ma
ny of these radio applications are also severely size and weight limited. Theref
ore, the digital platform design of both hardware and software must take into ac
count size, weight and power(SWAP) as primary design considerations. This paper
discusses best practices for hardware and software design in SWAP constrained r
adios. Topics covered are dynamic clock scaling, power supply scaling, modes of
operation, duty cycle impact, static versus dynamic power, hardware power reduct
ion considerations, and programmable logic versus ASIC designs.The work in this
paper provides reference for building flexible software defined radio(SDR) archi
tecture. |
