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
What type of modulation used in TV?
In cable TV, we use frequency multiplexing but in DTH, we use PCM along with quantization.
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 of the three multiplexing techniques arre used to combine digital signals?
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
What is frequency domain modulation?
Do you mean FDM or Frequency Division Multiplexing? If so, FDM is the division of a high frequency carrier into separate non-overlaping bands to be modulated by separate inputs. It's the modulation of several low frequency channels onto a high frequency carrier. Voice channels are low bandwidth inputs relative to the broadband carrier used to broadcast them.
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
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.
