Since the concepts of digital coding metasurface and programmable metasurface were put forward in 2014, the physical world of electromagnetics has been closely connected to the digital world of ...

正交频分复用OFDM是什么意思？ 正交频分复用 (Orthogonal Frequency Division Multiplexing-OFDM) 是宽带数字通信的常用调制方案。它使用许多间隔很近的正交子载波信号并行传输数据，其中每个子载波信号都采用各自的调制方案。 OFDM 提供频谱效率、抗多径干扰性和零载波 ...

Index modulation (IM) in orthogonal frequency division multiplexing (OFDM) systems represents a transformative approach in modern communications. This technique utilises the indices of active ...

Abstract: While many questions still surround the creation and deployment of the smart grid, the need for a reliable communications infrastructure is indisputable. Developers of the IEEE 1901.2 ...
