2.3 Characterization of the mobile channel
2.3.1 Statistical characterization of the effect of shadowing (slow fading)
Statistical characterization
2.3.2 Fast fading:
2.3.2.1. Multipath propagation: delay spread, coherence band, channel distortion: involvement of fading frequency channel on the data sent.
2.3.2.2. Effect of the movement of the terminal: Doppler spread, coherence time, fading channel in time domain (time-varying channel).
