Channel Models A Tutorial - Washington University in St. Louis

Feb 21, 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.
