Hi, I have two questions.
First, I am observing 32 words header in the soft slicer output. What does the header mean? I can't find it in the BCP’s user guides.
Second, , I found that the LLR mismatch at the last 2 symbol position in every column index in case of 1 RB test.
My test parameters are given below. (The project is used the BCP test project, I checked the partially de-interleaved input to BCP.)
SNReven = SNRodd = 1.;
rms = 1024;
Q format : 0
QPSK, 1RB,
The remaining parameters are same as that of BCP test project.
The input data = {
