Orthogonal Time Frequency Space (OTFS) modulation is a two-dimensional waveform design that offers a robust approach to signalling over doubly dispersive channels. Unlike conventional multi-carrier ...

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 ...

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 ...
