The effects of signal propagation are part of the trans-mission path for all radio signals. However, with the proliferation of digi-tal modulation formats (some very complex), pro-pagation effects play a much larger role. In fact, dealing with such issues as fading and multi-path are primary considerations in baseband signal processing. This brief tutorial identifies the issues in signal propagation that affect today’s wireless communications systems.
