What is mean by orthogonal frequency code division multiplexing in wireless communication?
Orthogonal frequency division multiplexing is special case of frequency division multiplexing where a ling serial data streams are divided into parallel data streams and each data stream is multiplied either by orthogonal frequency or code. when multiplied by code known as frequency code division multiplexing and when multiplied by orthogonal frequency then know as orthogonal frequency division multiplexing

What is 'ofdm'?
Orthogonal frequency-division multiplexing
Which of the three multiplexing techniques arre used to combine digital signals?
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
Orthogonal Frequency Division Multiplexing is a multi-carrier modulation scheme The data is?
Split up among several closely spaced subcarriers.
Why broadband are used in frequency division multiplexing?
Frequency division multiplexing is when a communication medium divides its frequency in order to carry a number of different signals at once. Broadband DSL uses this to transport large amounts of data quickly.
Name the various types of multiplexing techniques?
Multiplexing techniques vary widely based on what is being multiplexed. Modern telecommunications use a very wide array of techniques including: TDM - examples: TDMA, T-carrier FDM - examples: DWDM Spatial - example: MIMO Code division - examples: CDMA Phase or polarization division - cable/satellite TV Statistcal - examples: packet mode (STS), FHSS etc etc. This is far from a complete list. I think the question needs to be more specific.
Which of the three multiplexing techniques are used to combine analog signals?
Frequency-division multiplexing and wavelength-division multiplexing
What is meant by the term OFDM?
OFDM means Orthogonal frequency-division multiplexing. This is a method on encoding data which in digital television and radio. It is also used on 4G networks.
What is ofdm symbol?
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.
What is OFDM training symbol?
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.
Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
What is the definition of the word 'multiplexing'?
Multiplexing is the process of combining multiple signals over one media line. There are several types of multiplexing: frequency division, time division, and wavelength division.
What are three common examples of frequency division multiplexing?
AM radio broadcasting uses frequency division multiplexing to allocate different frequencies to different radio stations. Cable television systems use frequency division multiplexing to transmit multiple channels simultaneously over a single cable. Cell phone networks use frequency division multiplexing to separate different users' calls on the same frequency band.
