The performance of DSSS systems in the presence of multipath is described further in a separate section below. Modulation Technique Modulation technique is a key consideration. This is the

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.
