2x2 MIMO-OFDM channel estimation using pilots

Hi all, I am trying to estimate the channel in frequency domain of a 2x2 MIMO channel The problem is the way i insert pilot is like this: at the position on antenna 1 where a pilot is installed, on the same position on antenna 2 i put a zero , to ease LS channel estimation. But this causes a pb when i have to calculate the normalized MSE as the denominator will have some zero

HELP please, those who have experience in channel estimation!!!!!! Thank you!
