Abstract
We review progress in developing software-defined radio communication systems through using superconductive rf and digital technologies. Both the outstanding sensitivity and high spurious-free dynamic range (SFDR) of the state-of-the-arts superconductor analog-to-digital converters (ADC) enable broadband receiving systems with direct signal digitizing and subsequent digital extraction of sub-bands. To raise the overall system performance up to the outstanding performance of superconductor ADC, one can use an active superconductor electrically-small antenna (ESA) instead of standard passive antenna with a low-noise amplifier, both providing lower performance as compared to the ADC. The attainable characteristics and design issues of the superconductor active ESAs are reviewed and discussed.
我们回顾了利用超导射频和数字技术开发软件定义无线电通信系统的进展。最先进的超导模数转换器（ADC）具有出色的灵敏度和较高的无杂散动态范围（SFDR），可实现宽带接收系统的直接信号数字化和随后的子带数字提取。为了提高系统的整体性能，使其达到超导模数转换器的卓越性能，可以使用有源超导电子小天线（ESA）来代替标准的无源天线和低噪声放大器，两者的性能都低于模数转换器。本文回顾并讨论了超导有源 ESA 的可实现特性和设计问题。
期刊介绍：
Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity.
The main goal of the journal is to publish:
1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods.
2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance.
3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices.
The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
