Yes you are absolutely right, that’s a good & valid point.
But I wonder by how many dB’s the SCPIR is improved ? max 2dB I would say ?
Also, this software enhancement might actually benefit the paired MS too :
If a VAMOS-I MS is paired with a SAIC MS, then both are equally enjoying the orthogonality of their TSC. In this case, the SAIC MS is as efficient as the VAMOS-I.
But when a SAIC is paired with a SAIC, that’s where there is a slight degradation.
It’s great to discuss with you because you are very educated & have a very sharp mind 😉
