Webchannels were line-of-sight (LOS) or fading. 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. http://www.comlab.hut.fi/opetus/227/2005/7_227_2005.ppt hm jaime iii parking
