Be aware that the example showed is a SISO (Single-Input Single-Output) vs a SIMO (Single-Input Multiple-Output) configuration. There's no MIMO showed here. A MIMO configuration has always at least two antennas at BOTH transmitter and receiver. Bear in mind this omission should you use this video as a reference.
I think he is talking about MRC in the second part which is one of the features MIMO has.Actually, I am not even sure whether we can talk about MRC when the transmitter uses 1 antenna and probably does not support .11n. I agree the example could be a bit confusing. The video is 10 years old though.
I am thinking about doing my final year project in MIMO process control systems, but I am afraid as they are very complex and risky. what do you think ?. I am final year electrical and electronics engineering.
on uplink, can multiple single antenna stations transmit simultaneously ? the way i see it 802.11ac can transmit downlink to multiple stations at the same time but receiving is only possible from 1 station?! (802.11ax will fix it but for now multi 802.11n and 802.11ac can receive from only 1 station at the time regardless the number of antennas) if there is an engineer here reading this please give me your input.....

besides of new methodes of modulations tdma etc... the efect is the same .... the ocupation of the fisical frequency specttrum before others and lead the industry, sell more and kill old fashion forms of telcom designs ever... I dont know if you understand what I am talking about...?
they explore open spaces in both polarization infesting the spectrum... realy a plague in the air lol... where we could find some sanctuary using diferente polarizations to get thru .... forget it is infested by these radios...
it could be nice... but it is all wrong... the mimo radio indeed has 2 antenas, but they are not to explore reflected or spurious signals... they are designed to use the efect of the 3db signal separation between the horizontal and vertical polarization. one antena is horizontal and the other vertical and they exchange tx and rx at the most better performance dictaded by the wimax protocol...only a telcom engineer who has studied the maxwell equations know that... not a IT mam... on my personal note ubiquit stole ideias from mikrotic like nstream and mounting radios on the back of antenas as we always did in the field the are good observers... with a industry behind them... sorry my bad english
