Hi all,
I am trying to implement channel estimation using LS estimators for poweline. However, my channel estimation is based on preambles. On the TX side, based on the standard I have preamble transmitted on 36 subcarriers (out of total 128 subcarriers). I have 8 such OFDM symbols which makes 1 preamble. So my tranmission format will be
1 Frame = (Preamble = 8 OFDM symbols) + (header = 10 OFDM symbols) + (data = 22 OFDM symbols)
Now my question is how can I estimate the SNR using the preamble? I know how the LS estimators work. But I need an idea of how it can be implemented using preamble as I described before.
Any suggestions will be appreciated.
