Time-frequency duality 来自 Semantic Scholar 喜欢 0 阅读量: 88 作者: P Bello 摘要: This paper develops a concept of duality, called time-frequency duality, which is applicable to a class of networks called communication-signal-processing networks. Such networks consist of an interconnection of ...
The concept of Bello's time-frequency-duality is investigated in the paper. The time and frequency descriptions of systems were defined by Bello as dual descriptions. He assumed that a dual description of the input output behaviour of linear systems is always possible. However it is shown that...
In this paper, space-frequency-Doppler coded OFDM (SFDO-OFDM) scheme over the time-varying Doppler fading channels via the time-frequency duality is propos... Jiangzhang Zhu a,Shuangchun Wen a,Qingsong Du a b - AEU - International Journal of Electronics and Communications 被引量: 16发表: ...

We propose a purely analog way to time reverse optically-carried radiofrequency signals. Taking advantage of the time-space duality, we implement an approximate temporal imaging device that combines a time-lens and a single dispersive line. For military applications, this dispersive element must offer...

2) time-frequency duality 时间-频率对偶性3) time interval coupling pair 时段偶对 1. In the method the time interval coupling pair decoupling substitutes the time interval decoupling during the optimizing proce. 为此,该文提出偶对优化潮流方法,在优化过程中,用时段偶对解耦替代时段解耦。
