I got confused. So, Wireless standard a.b.g. use "ANTENNA DIVERSITY" with "STBC" and Wireless standards n + ac use "MIMO" with "SPATIAL STREAM and "CSD" ?!. Because i thought that when you talked about antenna diversity you clearly distinguished it from MIMO. ( 05:05 "antenna diversity does not use spatial stream")
thanks sir for your video, I have a doubt, in spatial multiplexer diagram , how the receiver would know the order of data is 1,2,3.....9. As it does not receive signal in order, how it arramges in order?
your explanation on space-time block coding is not correct. STBC involves sending different data streams on different transmit antennas (spatially) and then re-sending this same data on a second time slot but swapping the antennas you used to send the data in the first time slot. That is why it is called space-time because it sends the same data on different spatial paths and different time slots..
Please prepare one session on Coding and Modulation techniques used in Wi-Fi
Please include comparison between various type of frequency bands used in 802.11.
Can i have this PowerPoint please ?

Receiver runs the checksum to identify the order of data.
