Intelligent and green radio transmitters for broadband communication systems

点击翻译按钮获取中文摘要

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.
