Dear Sir,
I need to create a interpolator block which has a callback function to
change its interpolation factor on the fly.
If this block is inherited from gr::sync_interpolator, its interpolation
factor cannot be changed on the fly because the interpolation factor is an
argument of its

Hi Martin,
Thanks for your advice.
Although it is not so clear, I have some elementary ideas on this
project and I'm on it now. On the other hand, I will keep an eye
Hi Zhou - Can you post some links to relevant papers / research, for folks like
me to do a quick look at? I studied MIMO just a little bit, mostly from an IT
perspective, not a practical one. But, I've read through a lot of papers (on
many subjects) and would be interested in knowing more

Hi Zhou - I think it would be great to see how far GNU Radio can be pushed with
respect to MIMO processing. With advances in both algorithms and multi-core
CPU raw processing capabilities, the added computational requirements for MIMO
might be realizable at some reasonable level (IIRC, they
Hi Tom, thanks for your replay.
In fact, I'm not sure which are the sample rates of the example files
I'm using:
capture_941.8M_112.cfile
vf_call6_a725_d174_g5_Kc1EF00BAB3BAC7002.cfile
However, I've tried with different decimation rates, including typical
112, and nothing happens.

I just upgraded my ports-installed version of GR 3.6.3 to
GR 3.7.2.1 with a simple port upgrade gnuradio.
The install went smoothly without errors and installed
a working copy of 3.7.2.1 with only a few operational
issues.
Hats off to Michael Dickens for his superb job of supporting
GnuRadio on
Dear Martin,
Thanks for the hints.
I think this function helps: set_min_noutput_items()
Problem:
Says, the instantaneous interpolation_factor is 3.
As inherited from gr::block, the scheduler may call the general_work() with
noutput_items=2 (any number is possible).
When this happen, there is

I was setting up a flowgraph in GRC using the
mpsk_receiver_cc block and encountered a problem.
Don't know if it is a bug in the GRC xml or a
missing method in the block code.
In GRC, the mpsk_receiver's loop_bandwidth parameter
is underlined in the properties popup,
Where did you find that particular install?

After the make test failed for this module, I decided to poke around to see
if there is an easy fix. I made a script that simply executes the test over
and over until it seg faults and exits after the core file is created.
