Thank you -Burak Burak, There hasn't been much work (or interest that I've seen) in making this work. There is this page: http://docs.scipy.org/doc/numpy/reference/swig.interface-file.html It has information about how to pass numpy arrays through Swig. From my reading of it, though, it doesn't seem to really be applicable to how things are defined in GNU Radio. If someone were to make a go at getting it to work generically with our blocks, I'd like to have a look. Any time I work with numpy/scipy arrays, I just pass them through by calling the tolist() method on the array. This returns a Python list that works correctly with GNU Radio blocks.

Re: [Discuss-gnuradio] ATSC decoding - Now Working!
Alright. If I get it working I will post my fixes. Which part is not working? Also, my research only deals with extracting the bit delay to the data sync frame. So, I will not really be doing much with atsc decoding past getting a bit stream what would include the sync frame. Which also brings up another question. In the general signal flow of decoding the atsc with gnuradio, when will the data sync frame be uncovered? At the moment, I run interp_short, xlate, and fpll. Those translate the signal to baseband and I think fpll demodulates. Do any of you guys happen to know what fpll actually outputs? Like what form is the data in? Because I don't have real over the air data to run through this I can't crack it open to make sense of it. Is it raw binary bit stream after that stage? Again, my intuition is that fpll outputs the raw bitstream and to find the data sync frame I will be able to just run a binary correlator with the pn_511 sequence. Any advice would be helpful.

Tom, Am I correct in assuming you are running GR.org on AWS? I have noticed in my own use of AWS that they have occasional scheduled reboots of their hardware for upgrades, which naturally causes a reboot of your instance. These scheduled events are listed in the AWS console page. A scheduled maintenance reboot may have caused the short outage Marcus saw. On 02/18/2012 01:22 PM, Marcus D.

[Discuss-gnuradio] Anyone have an opinion on what existing block is closest to the attached so that I can start writing my own?
Attached is a C implementation of a block I wish was in Gnu Radio.
Anyone done anything similar-enough as a block
in Gnu Radio that would make a decent starting point?
It's basically a block that takes a fixed-size vector input, and a list
of descriptors that describe output channels that need to be carved out of
the input vector (a list of start:end which are simply offsets into
the vector). It's intended to be used after a FFT+complex-to-MAG block to
process the resulting vector and select sub-bands and turn them into
power-estimate channels. I see nothing in Gnu Radio that does this,
other than things like the FFT channelizer, PFB channelizer, etc.
Neither of those is efficient in this case, because the channels are of
non-uniform distribution and width, and if the target is simply power
estimation, that part has already basically been done by the
FFT+complex-to-MAG stage.

/*
* A specialzed vector de-mux for estimating power within defined sub-bands of
a vector that
* is the output of an FFT+complex-to-MAG
*
* It takes in a fixed-size float vector, and a list of descriptors describing
the sub-bands that are to
* be added together to form an output channel. The output is a number of
channels (one per descriptor).
*
* Consider the following example:
*
* Input vector:
*^^ ^^^
* CH 0 CH 1CH 2(etc)
*
* For simple multi-channel power estimation this is significantly more
efficient than many other techniques
* that might be used. Channel-width resolution is based purely on the
resolution of the FFT+complex-to-MAG
* that feeds this specialized demux. Resolutions of a few hundred Hz with
25MHz input bandwidths appear to
* be feasible with this technique. For uniformly-spaced channels with
relatively-coarse resolution, a PFB
* channel bank might be better.
*
* This rides on the fact that the Gnu Radio FFT implementation is very
efficient, due to its use of
* FFTW, which provides several overlapping techniques to improve performance
including:
*
*o an optimizer
*o aggressive use of SSEx/3DNow! instruction sets
*o multi-threaded FFT calculations (useful for very large FFTs, which are
required for fine resolution)
*
* In many situations, the total number of post-FFT ops you need to do is quite
modest compared to the FFT,
* since you may be ignoring the vast majority of the input vector. In the
application domain of interest
* (multi-channel power estimation for ionospheric measurements), probably
98% of the input vector isn't
* touched. But the channels of interest are:
*
* o not evenly spaced
* o not of uniform bandwidth
* o between 1 and perhaps 10 sub-band collections (output channels)
might be of interest
*
* invector - input vector of size 'vecsize'
* vec_begins - list of sub-channel start points (offsets from beginning of
input vector)
* vec_ends - list of sub-channel end points (offsets from beginning of

I don't have access to an OSX box or an E100, so I can't really test this out. The files you sent me don't (appear to) tell me what the real problem is. We'll need some other brave soul out there who can dig into these issues on the platforms for us. Those are functions I wrote, so they're my problem. =) I'll hack on it this week.

We are interested in determining the best architecture at instantation time. What would be the best strategy? We though about running the same operations several times for each architecture, measure the results and use the fastest one for the processing blocks. Would this be the right approach? Carles, Run volk_profile. It does exactly what you said, and writes the results to ~/.volk/volk_config. Volk reads this file when it is involked (sorry) to determine which particular function to execute. So all you do is run volk_profile once on any given machine, and it's optimized. --n Carles, This is discussed on the webpage: http://gnuradio.org/redmine/projects/gnuradio/wiki/volk We'll be updating this as things progress with Volk, but the profiler info is there already.
