HI , i am doing a project on channel estimation in ofdm . I want to estimate the SNR of the recievd symbol using the preamble symbol.

Please let me if i can do this in GNU radio. 

 http://gnuradio.org/doc/doxygen/group__snr__blk.html Tom created and blogged about two blocks to do SNR. I've had success using both for PSK signals. One is a probe that generates messages. The other is a pass through that generates tags.
