I'm looking benchmark program and now found use of gr.firdes.low_pass:
chan_coeffs = gr.firdes.low_pass (1.0, # gain
sw_decim *
self.samples_per_symbol(), # sampling rate
1.0,
Thanks for your response. Please see below.

I'm using RFX900. Does it employ the same mechanism to be disabled between
bursts? I thought it gets disabled after an end-of-burst packet. (Perhaps I'm
doing something wrong with my burst code, but I'm pretty sure I send an EOB
packet)
Thanks,

I'm not sure whether this is a GNU radio or USRP issue, so I'm posting to both
lists. I played around with GNU radio's stream tagging feature and managed to
implement something that does timed bursts (partially by taking a lead from
tag_source_demo.h, etc. in gr-uhd/examples).

Dear all,
I finally figure out how to receive packet using OFDM and Alamouti but
unfortunately looks like I cannot detect all the peaks.
10% of the packets that I receive are right.
I think that I experience a phase rotation, i.e. instead of receiving
-1, I receive +1 for some preamble symbols and
If there is no samples flowing into the wav file sink block would work() be
called? (IE, if there is a closed valve in front of the wav_file sink)

I've updated 'simple_ra' on CGRAN to support FCD. But since I don't
have an FCD, I can't really
test it.
The FCD variant of the startup script is called 'simple_ra_fcd'.
You'll need to build/install gr-fcd prior to installing simple_ra
