I am not an expert in signal processing but last week I attended a class of signal processing. We discussed MIMO, OFDM and Alamouti scheme.
On this lecture it was represented a lot of math equations, but wasn’t explained where and it is used in practice.
I asked and got the following answer: “MIMO OFDM is considered a key technology in modern wireless-access communication systems such as 4G or 5G. IT used for high data rate transmission…”
Ok, I can read the same information in all websites about this topic. But we have to understand not all theory in signal processing could be implemented(used) in practice.
- What the practical use of MIMO OFDM is for me understandable. If I implement a receiver or transmitter or transceiver, my two channels (2 input of antennas) are MIMO system.
- Alamouti scheme, how does it use in practice? I have read some post: post 1, post 2
and I don’t understand if it is usable or it is just theoretical concept?
