The ad tool divides people up by region, but because these two sets of users are by nature moving around (work may be in one place, like Washington D.C., and home in another, like Virginia) counting them becomes ambiguous.
Although the spatial diversity and the code diversity have been applied to distinguish different users, the communication signal still can corrupt the ranging signal for the same user because these two processes use the same SS code.
That is to say when the signaling between two users stops because one of them stops responding, despite there having been a degree of priorly stated mutual interest.
where only two users can be used because the number of transmit antennas defines the number of orthogonal users that can be served simultaneously.
Based on this, the weighted channel gains of the scheduled users result uncorrelated, that is, E ( g 1 T · w 1 ) * ( g 1 T · w 2 ) = 0, (23) where only two users can be used because the number of transmit antennas defines the number of orthogonal users that can be served simultaneously.
That's good news, then, because 3 million users pales in a time when some industry folks are proclaiming 10 million is the new 1 million.
The performance of the adaptive algorithms is better than the previous case because four users require a throughput guarantee that is less than Bopt/WT W = 0.5675 bits/s/Hz of the identical throughput guarantees case.
Having asked "why" Wikipedia is so popular, he writes: "Because it has 2.2 million users, and because it's very often the first hit in a Google search, and because it just feels good to find something there".
Because we can, 6 million users (and growing rapidly) are sharing bite-size pieces (140 character limit) of their lives with friends and strangers.
Because of its 950 million users, an Oscar winning movie based on its founding story and an ecosystem of other companies built off of it, Facebook enjoyed one of the most anticipated IPOs ever.
