An unguided signal can be split into several transmission paths, with each path experiencing different impediments (e.g., reflection, scattering, etc.), thus causing each path to vary in length. This results in several copies of the signal reaching the receiver at slightly different times, thus leading to signal distortion. This is termed multipath fading.

Low SNR is preferred in a communications link, since it means that the noise will also be low.

Using a direct sequence spread spectrum (DSSS) technique spreads a narrow band channel so that it occupies greater frequency spectrum. By doing this, the signal has greater immunity from narrow band noise.
