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

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 ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last year. Click-through for the notes or check out the video below the break ...

Over the past several years, orthogonal frequency division multiplexing (OFDM) has received considerable attention from the general wireless community and in particular from the wireless LAN (WLAN) ...

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 ...

Access methods are multiplexing techniques that provide communications services to multiple users in a single-bandwidth wired or wireless medium. Communications channels, whether they’re wireless ...
