I have been wondering about how we can estimate the SNR in Wideband MIMO measurement system? So far, I analyze the average path gain in all snapshots, I choose the lowest path gain snapshot as the noise level. My SNR will be the average power (power of channel matrix) divided by this noise level. Is this correct approach?

Dear Dwi Joko Suroso
In Wideband (Broadband) MIMO communication system the channel matrix represent as a polynomial form, in order to understand polynomial channel matrix decomposition (time-domain and/or frequency-domain) techniques, I'll recommend you to read following articles

The SNR at each Rx antenna is different due to sub-channel gains or waterfilling power allocation, so you should calculate SNR at all receiver antennas individual the summation present system SNR
