Small Scale Fading Scale Fading

Hello Researchers, In this section we will discuss about “Small Scale Fading“. In Mobile Radio Propagation specially in Wireless communication it is very much important topic for Researchers.  

Small Scale fading: Small scale fading or simply fading is used to describe the rapid fluctuations of the amplitudes, phases or multi-path delays of a radio signal over a short period of time or travel distance.

Fading is caused by interference between two or more versions of the transmitted signal which arrive at receiver at slightly different times.

These waves are called as multi-path waves combine at receiver antenna to give a resultant signal which can vary widely in amplitude and phase, depending on distribution of the intensity and relative propagation time of waves and bandwidth of transmitted signal.

⇒ 1.Three most important small scale fading effects are: Rapid changes in signal strength over a small travel distance or time interval

2.Random frequency modulation due to varying Doppler’s shifts on multi path signals

3.Time dispersion (echoes) caused by multi path propagation delay.

There may be some more documents on Small Scale Fading, this article is written by taking the help from Internet and other resources like Books, journals etc.
