Although I created an account (Alexdu) in case I can be added by you.
In case you couldn't already, now you can post.

I don't understand the question.

Hey,
i changed tx_ofdm and rx_ofdm to communicate through a fifo (named

Hi all,
thank you Tom for that fast response.
I would like to clarify some additional stuff:
I want like first to design signal shaping filter. Can you give me some
guidlines, like 1.5 of the symbol rate or similar. I am currently playing
with the filter design tool, quite nice tool, but can't do
Most interesting! Thanks for sharing!

Hi Marcus,
Very nice. We've also been looking at using the $8 RTLSDR as a educational
tool to do exactly the same thing.
Alan Rogers et. al. at Haystack have also developed something similar:

Yes, I'd seen both this, and the earlier SRT.
Dear Marcus,
thanks for sharing this document. It happens that I'm writing a paper about
the use of RTL2832U-based dongles applied to software radio (well,
specifically about their use as GNSS receivers), and I would like to
reference your work on radioastronomy as a example of other possible

Installed gnu radio using mac ports. First attempt was bumpy, so unistalled and
reinstalled again.
The companion comes up, but when I try a simple FM receiver (RTL-SDR - WBFM -

Hi Dan - Make sure you've installed both the gnuradio and gr-osmosdr ports with
the +swig variant. Without it, you do not get the *_swig import libraries. If
this is not the case, then email me off list and I'll help you debug the issue.

I think my question would have been clearer if i had said that when I

fft_length+CP_length, but its fft_length+CP_length components.
So for me symbol rate is

I do have a bunch of files written in python and C/C++ describing a complete

However I am intending to add new features from the FPGA API

Here are the additional details..

Also,kindly find the attached grc file i am using.
Please let me know if more details are required..
