Multipath interference is a phenomenon in the physics of waves whereby a wave from a source travels to a detector via two or more paths and the two (or more) components of the wave interfere constructively or destructively. Multipath interference is a common cause of "ghosting" in analog television broadcasts and of fading of radio waves. The condition necessary is that the components of the wave remain coherent throughout the who… Web12 nov. 2015 · Question 1: Yes, it is a multipath Rayleigh Channel with $ 1000 $ taps.
