Intelligent and green radio transmitters for broadband communication systems

未来的通信网络将需要比今天更加无处不在和灵活。还需要它们来支持多标准通信环境中对移动性和高吞吐量要求的大量需求。这增加了无线和卫星通信设备对功率和频谱效率的严格要求。因此，未来的无线电系统必须被设计成满足所有上述关键能力。虽然多频带接收器和低功率手持终端在市场上是可以买到的，但是在带宽、线性度和功率效率方面，它们用于无线和卫星通信应用的基站和中继器的高功率对应物很难在所需性能内设计。

Future communication networks will need to be more ubiquitous and agile than they are today. They will also be required to support the large demand for mobility and high throughput requirements within the environment of multi-standard communications. This adds up to the stringent power and spectrum efficiency needs of wireless and satellite communications equipment. Accordingly, future radio systems have to be designed to meet all the above mentioned critical capabilities. Although multi-band receivers and low-power handheld terminals are commercially available, their high-power counterparts for base stations and repeaters for wireless and satellite communication applications are difficult to design within the required performance, in terms of bandwidth, linearity and power efficiency.
