Chapter 6: Small-Scale Fading and Statistical Channel Models

Learning Objectives

• Explain how multipath propagation causes small-scale fading
• Derive the Rayleigh and Ricean fading distributions from physical principles
• Relate Doppler spread to coherence time and mobile velocity
• Compute RMS delay spread and coherence bandwidth from a power delay profile
• Classify channels as flat/frequency-selective and slow/fast fading
• State and apply Bello's four system functions and their Fourier relationships
• Construct the tapped-delay-line discrete-time channel model
• Describe standardised channel models (3GPP SCM, WINNER, QuaDRiGa)
