Hi all,
In ofdma the preamble is of 2 symbol long first one consist of 4 shorth
and then long of some sequence.
how do we use second symbol preamble (or long preamble) to find the freq
response of channel to train equalizer? currently when i do a cross
correlation of a preamble received after channel with known sequence of
preamble i don't see the frequency response of the channel am i doing
something wrong??
