Diversity combining devotes the entire resources of the array to service a single user. Speciﬁcally, diversity schemes enhance reliability by minimizing the channel ﬂuctuations due to fading. The central idea in diversity2 is that diﬀerent antennas receive diﬀerent versions of the same signal. temperate vs tropical grasslandsWebJun 5, 2012 · Diversity combining exploits the fact that independent signal paths have a low probability of experiencing deep fades simultaneously. Thus, the idea behind diversity is to send the same data over independent fading paths. These independent paths are combined in such a way that the fading of the resultant signal is reduced. temperate rainforest wa
