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 ...

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 ...

Orthogonal frequency-division multiple-access provides Wi-Fi 6 with high throughput and more network efficiency by letting multiple clients connect to a single access point simultaneously. Wi-Fi 6, ...

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 ...

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) ...

Imagine that you had to send different letters to multiple friends, but all at the same time. Sending every letter individually, obviously, would end up taking a lot of effort and time. So, instead… ...

Multiplexing is a technique for carrying multiple channels of information within a common signal. Although usually thought of as a digital process, the method was actually pioneered many years ago as ...

Generalized Frequency Division Multiplexing (GFDM) is a flexible, block-filtered multicarrier modulation scheme that extends the principles of Orthogonal Frequency Division Multiplexing (OFDM) by ...
