Web21 feb. 2007 · propagation through the channel H becomes y: y(f)=H(f)x(f)+n(f) Here H(f) is channel response, and n(f) is the noise. Note that x, y, H, and n are all functions of the signal frequency f. The three key components of the channel response are path loss, shadowing, and multipath as explained below.

Outdoor propagation model. 2. Indoor propagation model. 4.1 Outdoor propagation models In the mobile communication system radio transmission often takes place over discontinuous terrain. The terrain profile may vary from a simple curved earth profile to a highly mountainous profile.
