Hi,
I'm still trying to gener= ate test vectors for the bbdev application within=C2=A0
DPDK. Mor= e precisely, I want to create a test vector to run an LDPC decoding operati= on.

For that, I'm generating the LLRs with mat= lab (5G NR toolbox) as follows:
=C2=A0 1) LDPC encoding=C2=A0+ ra= te matching=C2=A0+ modulation
=C2=A0 2) Demodulation=C2=A0+ rate = recover

The generated LLRs vector is directly deco= dable by flexRAN DPDK but when using it through=C2=A0
bbdev, it t= akes max iterations to decode, meaning that the decoding process was=C2=A0<= /div>
unsuccessful.

Any ideas/documentation ab= out how to properly create the test vectors?
