Why multichannel beamforming is useful for wireless communication

- Wireless communication systems like 5G and WiFi usually have to serve many users simultaneously and they have to deal with multiple paths between two radios when operating in a scattering rich environment. This video covers how multichannel beamforming and spatial diversity is used to overcome those issues.

multichannel beamforming is also used in fighter aircraft and a good example would be the TWS radar mode ( track while scan ) where there is a beam locked on one or more enemy targets and another still scans the sky to potentially detect other targets
It is such an amazing explanation!
Glad you liked it
Excellent, thank you
excellent explanation. thank you
Glad it was helpful!
Some great stuff here
hi Brian, Thanks for the well explained video. If I got it right in the case when we are supposed to simultaneously cover multiple radio receivers with a single array, multiple dedicated beams need to be sent for each receiver which means different RF chains are required for each one in a hybrid beamforming scenario right?
That is useful discussion for downlink but does not apply to uplink. Is there a video on Uplink receiving signals on all those array elements.
Can an embedded Extruded aluminum T-slot channel be used for this system?
Hi Brian, can you please do some videos on the Lyapunov Stability Theorem and Sliding Mode Control?
It would be greatly appreciated since I am dealing with a problem that can be solved via SMC.
So this is how fighters lock radar missiles onto multiple targets simultaneously.
Nothing commercial about massive mimo. In fact, more then 4 ant elements is less economically wise
