What is fading in telecommunications?
In wireless communications, fading is deviation or the attenuation that a carrier-modulated telecommunication signal experiences over certain propagation media.
What is channel impairment?
Channel impairment in signals transmission: Noise, fading and distortion etc. that result in transmission quality degradations.
What is multi-path fading?
Multi-path fading is a phenomenon in wireless communication where signals travel through multiple paths to reach the receiver. This results in signal reflections and interference, causing the received signals to experience fading or fluctuations in amplitude and phase. Multi-path fading can lead to degradation in signal quality and can be mitigated using techniques such as diversity reception and equalization.
What has the author Mohammad Javad Omidi written?
Mohammad Javad Omidi has written: 'Structures for kalman-based detection over rayleigh fading channels'
When was Fading In Fading Out created?
Fading In Fading Out was created in 2005.
What is time selective fading?
time variation of transmission channel due to changes of envirenment and the effect of Doppler to transsmited signal
Why 802.11use acknowledgements but not in wired Ethernet?
Two scenarios exist where a wireless network might not know if a frame was successfully delivered, that do not exist in a wired network. First, a weak wireless signal could mean that the sender may not be capable of transmitting and listening at the same time, and this makes collision detection impossible. Second, fading or the hidden-terminal problem could mean that interference occurred during the transmission without the sender knowing.
What is meant by frequency Interleaving?
Frequency interleaving is a technique where consecutive symbols in a data stream are spread across different frequency subcarriers in a communication system. This helps combat frequency-selective fading in wireless channels by reducing the impact of frequency-specific signal impairments. By spreading the symbols across multiple frequencies, frequency interleaving helps improve robustness and reliability of the communication link.
What type of fading cause serious distortion of modulating signal?
selective fading
