Can you please guide me on the information to calculate SNR for OFDM Reciever? Is OFDM Pilots used for it? And do we need to follow channel estimation like steps of interpolation to determine it? I'm a little confused and where do we calculate it- Baseband Analog or Baseband Digital portion. Please point me to answers if already given specific to this question.
Already asked somewhat similar question before Where is SNR and CNR calculated for LTE? and this is an addition/more detailed question to it.
