Single-frequency network — For other uses, see SFN (disambiguation). A single frequency network or SFN is a broadcast network where several transmitters simultaneously send the same signal over the same frequency channel. Contents 1 Overview 2 OFDM and COFDM 3 DVB T SFN … Wikipedia
Dynamic single-frequency networks — (DSFN) is a transmitter macrodiversity technique for OFDM based cellular networks. DSFN is based on the idea of single frequency networks (SFN), which is a group of radio transmitters that send the same signal simultaneously over the same… … Wikipedia
Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… … Wikipedia
Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia
Single-carrier FDMA — (SC FDMA) is frequency division multiple access scheme. It can be viewed as a linearly precoded OFDMA scheme, henceforth LP OFDMA. Or, it can be viewed as a single carrier multiple access scheme. One prominent advantage over conventional OFDMA is … Wikipedia
Single-sideband suppressed-carrier transmission — Single sideband suppressed carrier (SSB SC) is a telecommunication technique, which belongs to the Amplitude modulation class.The information represented by the modulating signal is contained in both the upper and the lower sidebands. Since each… … Wikipedia
Hoher Meissner transmitter — is a facility for mediumwave, FM and TV broadcasting on Hoher Meissner mountain in Northern Hesse. Hoher Meissner transmitter was inaugurated in 1951.For the mediumwave transmission of Hoher Meissner transmitter from 1951 to 1995 a 150 metre tall … Wikipedia
single sideband — single sideband, Radio. a transmitter or system that uses only one of the two sidebands of a frequency, eliminating the carrier signal completely. A single sideband permits more frequencies to exist and requires less space between them … Useful english dictionary
Single Vegetative Obstruction Model — The ITU Single Vegetative Obstruction Model is a Radio propagation model that quantitatively approximates the attenuation due to the vegetation in the middle of a telecommunication link. Applicable to/under conditionsThe model is applicable to… … Wikipedia
Frequency mixer — This article is about non linear mixing operating in the frequency domain. For other types of mixers, see electronic mixer. Frequency Mixer Symbol. In electronics a mixer or frequency mixer is a nonlinear electrical circuit that creates new… … Wikipedia
Frequency synthesizer — A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie… … Wikipedia
