Hi,
any solution to the reception (rx) or tx of wimax using gnuradio?
could not find any proper chain that finds the preamble.

Hi Eitan,
it's been a while since I've looked into IEEE802.16, but that's a very
regular OFDM system, isn't it, with a fixed OFDM symbol as short
preamble (for the downlink bursts), and a 2-symbol preamble for the
start of frame?
A simple correlation detector might do in that case; a bit nicer on
Hi Eitan,
please keep replies on the list!
I don't think there's a readymade solution for you.
I'm not quite sure what you mean with "resemble OFDM": could you
elaborate? I really thought that IEEE802.16 is a pure OFDM system, so
this comes as a surprise. In which way is it not?
Best regards,

hello,
it is an ofdm system, but i could not get to tweak the ofdm_Rx example to
find the preamble in the transmission i was looking to capture.

Hi,
ah! OK, yeah, that's unfortunate.
So, the easy thing about OFDM: as soon as you know where your symbol
starts, all you need to do is apply an FFT – and you're done. (you will
still have to "equalize" your reception, but that is a point-wise
multiplication at the output of the FFT.)
So, if I
