You can calculate power both in frequency domain or time domain. but the prefered method is in time domain (i.e. after IFFT) . In simulink you may use square and moving average to calculate the signal power.

there is know ofdm symbol with cp
ofdm symbol includes cp..
so if u want to calculate mean square power measn its for each ofdm symbol not for ofdm symbol with cp..

wel to calculate consider the peak value of each ofdm symbol... and do the rest its straight forward

In simulink you may use square and moving average to calculate the signal power.
wel tats one of te option are else u can create a mat function block and insert after cp
