We have 5g Link Level Simulator. Our research are concerned with NOMA. I analyzed SignalConstellation.m. Here 3GPP MUST composite constellation parameters are present. ( From Line 38 to Line 43) I read MUST Category 2: Superposition transmission with adaptive power ratio section from 3GPP TR 36.859 V13.0.0 (2015-12) document. There I see transmission power ratios ( alpha) for a MUST-near user could be calculated. Below Link On Figure 1, example of the composite constellation of the MUST technique with quadrature phase shift keying (QPSK) modulation is showed.
Composite constellation of the MUST technique with quadrature phase shift keying (QPSK) modulation
So I calculated near user power ratios according to above Link for c_QPSK and d_QPSK parameters from SignalConstellation.m. For example for default c_QPSK and d_QPSK parameter ( MUSTIdx==2) , I calculated near user power ratio alpha as 0.1379. I wonder that you select this parameters according to a documentation or you select these parameters to adjust power ratios for near and far users random? How could I change MUST composite constellation parameters to decide different near user power ratios?
Best Regards…
