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 ...

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 ...

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique in which a high-rate data stream is divided into a number of parallel low-rate substreams, each modulating an ...

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

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 ...

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 ...

The IEEE’s latest standard, 802.11ax, has been designed inside and out for high efficiency. Also known as Wi-Fi 6, 11ax promises real-world performance improvements that will keep today’s mobile users ...
