MIMO
Spatial multiplexing, beamforming and diversity. These techniques can be combined to achieve different trade-offs between data rate, reliability, and complexity.
Dr.Hadj Abd El Kader Benzater thank you for your contribution to discussion
The different techniques used in MIMO to transmit and receive multiple data streams simu are:
-Spatial Multiplizing
-Beamforming
-Spatial diversity
-Space-Time coding
-Precoding

Somewhere on the internet, it's reported the maximum diversity gain limit theoretically can be achieved is 10dB. Some papers said it increases with more antennae and some said it will decrease.

I found various units at various literatures for CCL. In some figures I found it is placed as CCL (dB). But somewhere else the formula provided is - log(base 2)det(Br), here base is 2, also in...
