Small scale fading types
Did you know?
WebThere are four types of small-scale fading. They are flat fading, frequency-selective fading, fast fading and slow fading. Small-scale fading, depending on multipath time delay spread, can be flat fading and frequency-selective. In flat fading the bandwidth (BW) of the signal is less than the coherence bandwidth of the channel. Webroughly divided into two types (Figure 2.1): • Large-scale fading, due to path loss of signal as a function of distance and shadowing by large objects such as buildings and hills. This …
WebMar 29, 2024 · Small-scale fading is a fast-varying phenomenon that affects individual symbols or bits, while large-scale fading is a slow-varying phenomenon that affects the … Webpresent, such as a line-of-sight propagation path, the small-scale fading envelope is described by a Rician pdf [3]. A mobile radio roaming over a large area must process signals that experience both types of fading: small-scale fading super-imposed on large-scale fading. There are three basic mechanisms that impact signal prop-

Note: Unless there is possible confusion with large-scale fading we shall refer to small-scale fading as fading itself. Fading is the rapid variation of the received signal level in the short term as the user terminal moves a short distance.
