frequency division multiplexing การใช้

• Narrowband orthogonal frequency division multiplexing power line communicationtransceivers for G3-PLC networks.
• This is called frequency division multiplexing ( FDM ).
• At the same time as AM radio began, carrier frequencies, called " frequency division multiplexing ".
• There, they developed his theory into a technology called vector orthogonal frequency division multiplexing, or VOFDM.
• In addition, modulation has the advantage that it may use frequency division multiplexing ( FDM ).
• It is used in Frequency division multiplexing.
• Clarity built a MIMO demonstration link and developed a related technology, vector orthogonal frequency division multiplexing ( V-OFDM ).
• Methods were developed and deployed as far back as the 1970s to transmit analog video using frequency division multiplexing via fibre-optic cabling.
• While not being completely compatible with each other, the European and Japanese systems will both use a technique known as orthogonal frequency division multiplexing.
• More recently, Tarokh has also contributed to orthogonal frequency division multiplexing, cognitive radio and collaborative communications, pricing, scheduling, sparse representations theory and distributed beamforming.
• Before the digital T-1 system, carrier wave systems such as 12-channel carrier systems worked by frequency division multiplexing; each call was an analog signal.
• With ADSL, the modem and the DSLAM communicate by a protocol called discrete multitone modulation ( DMT ), which is a form of frequency division multiplexing.
• "' DVB-T "'uses coded orthogonal frequency division multiplexing ( COFDM ), which uses as many as 8000 independent carriers, each transmitting data at a comparatively low rate.
• Can u explain me in detail the pulse width modulation using frequency division multiplexing ?  Preceding contribs ) 02 : 24, 4 April 2011 ( UTC)
• A wide-band data link from the gateway to the user terminal employs an Orthogonal Frequency Division Multiplexing ( OFDM ) with a Time Division Multiplex ( TDM ) overlay.
• By using frequency division multiplexing, an HFC network may carry a variety of services, including analog TV, digital TV ( SDTV or HDTV ), video on demand, telephony, and high-speed data.
• Flash-OFDM, which stands for Orthogonal Frequency Division Multiplexing, has other attributes beyond speed : It was designed to work well in moving cars and trains while requiring less spectrum than some wireless technologies.
• Telephone trunk lines, and especially frequency division multiplexing carrier systems, are usually 4-wire circuits rather than 2-wire circuits ( or at least they were before fibre-optic became widespread ) and require a different kind of cable.
• Analog and digital modulation facilitate frequency division multiplexing ( FDM ), where several low pass information signals are transferred simultaneously over the same shared physical medium, using separate passband channels ( several different carrier frequencies ).
• At the core of the coalition is the technology called Vector Orthogonal Frequency Division Multiplexing-- which Cisco says delivers two-way data, voice and video communications over the air with speed and quality comparable to today's cable networks.
