Hi Alekh - I did a pull and I still can't compile gr-dpd using gnuradio-3.8.1.  I couldn't find anything cmake/Modules using grep for 3.7. But then I did a find and I found it in

  ./CMakeLists.txt:find_package(Gnuradio "3.7.2" REQUIRED)

So I chaged it to "3.8.1".

But when I attempt to build it,  I get this error

[  5%] Building CXX object lib/CMakeFiles/gnuradio-dpd.dir/add_guardbands_vcvc_impl.cc.o /opt/gnuradio/src/gr-oot/gr-dpd/lib/add_guardbands_vcvc_impl.cc:25:10: fatal error: gnuradio/io_signature.h: No such file or directory
 #include <gnuradio/io_signature.h>

So I'm punting.

Hello Community!!

I have updated the latest blog post for last week's updates. Here is the link: https://grdpd.wordpress.com/2020/06/06/week-3-addition-of-dpd-rls-algorithm-blocks/

Some of the highlights are:

- Addition of blocks for implementing RLS DPD Algorithm in gr-dpd module, namely:

  * stream_to_message

  * stream_to_gmp_vector

  * predistorter_training

  * RLS_postdistorter

- Addition of a Test flowgraph using above blocks.

Upcoming tasks:

- Thorough testing of the DPD blocks to ensure their working and prevent crashing for any corner cases.

- Working towards the debuging and improvement of RLS algorithm implemented in form of OOT blocks.

Any kind of suggestions or ideas on this project and my progress or work are highly appreciable.
