A demand-assign optical frequency-division-multiple-access star network

Journal of Lightwave Technology, 1993
This paper describes a demand-assign optical frequency-division-multiaccess (DA-OFDMA) star network that achieves efficient frequency utilization while offering an efficient assign control protocol. First, two OFDMA star networks are compared. One employs a frequency routing multiplexer and the other uses an optical mixer.

Bandwidth-Efficient Modulation with Frequency Division Multiple Access (FDMA)

2017
In a wide variety of communication systems, modulation as a fundamental technique plays a very important role in data transmission through air within a specified spectral bandwidth. A modulation signal, which is usually represented by a low-frequency baseband signal and is commonly referred to as an information-bearing signal, varies or modulates one ...

Orthogonal Frequency Division Multiplexing and Code Division Multiple Access Systems

2021
Abstract Chapter 8 presents modern multi-user and multicarrier communication systems based on code division multiple access technology and orthogonal frequency division multiple access technology. Analogue, digital, and discrete orthogonal frequency division multiple access systems are presented separately and then inter-related from ...
