Design of a self-routing frequency division multiple access (SR-FDMA) network using an optical ring filter with or without gain as a router

Journal of Lightwave Technology, 1995
Self-routing frequency division multiple access (SR-FDMA) network with ASK coherent detection and dual ring topology is proposed. The router, which employs the optical ring filter, is used as a means for selecting the desired channel carrier and at the same time as a bypass of the other channel carriers.

Frequency Division Multiple Access (FDMA)

Radio Frequency Multiple Access Techniques Made Easy, 2018
FDMA (frequency division multiple access) is the oldest communication technique used in broadcasting, land-mobile two-way radio, etc. It begins with a band of frequencies, which is allocated by the FCC (Federal Communications Commission). This band of frequency is further divided into several narrow bands of frequencies, where each frequency, also ...

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 ...

Fast-Chirp FDMA MIMO Radar System Using Range-Division Multiple-Access and Doppler-Division Multiple-Access

IEEE transactions on microwave theory and techniques, 2021
Frequency-division multiple-access (FDMA) in frequency-modulated continuous-wave (FMCW) radar comprises range-division multiple-access (RDMA) and Doppler-division multiple-access (DDMA). In this article, we present a method using RDMA and DDMA to realize

Enhancement of image transmission using chaotic interleaving with discrete wavelet transform‐based single‐carrier frequency division multiple access system

International Journal of Communication Systems, 2021
Long‐term evolution (LTE) system adopts single‐carrier frequency division multiple access (SC‐FDMA) technique for high data‐rate uplink wireless communication mainly due to its advantage of high power efficiency and low peak‐to‐average‐power ratio (PAPR).
