Hi BZS,

luckily, that's rather intuitive :) :
Using the complex to mag squared block you can get the sample "energy".
Using the max operation you can find the maximum in your vector
(==ofdm symbol), using integrate (with a decimation of vector length)
you get the the total power. The rest is just division.

Greetings,
Marcus
