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

In mobile underwater acoustic communications (UAC), the relative movement between the transceivers will cause Doppler spread in the received signal, which will bring inter-carrier interference to the ...

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 ...

As more high-speed amplifier applications deal with communication systems, wired or wireless, a brief introduction and overview of orthogonal frequency division multiplex (OFDM) is necessary. With a ...

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 ...

Over the past year I’ve been writing about potential transmission standards for a nextgeneration broadcast platform (NGBP). The most promising standards are all based on orthogonal frequency division ...

CableLabs has announced the certification of the industry’s first DOCSIS 3.1 Plus (DOCSIS 3.1+) device supporting four orthogonal frequency-division multiplexing (OFDM) channels. The certified device, ...

With the advent of higher broadband speeds in the fixed line and wireless systems, the need for higher performing data converters has become apparent. In this article, we discuss the different ...

A three day course on orthogonal frequency division multiplexing (OFDM) designed to present the complex mathematical theory associated with wireless systems in an intuitive and straightforward style ...
