I continue on the verification of the L2S model in a single-cell and single-user scenario. After modifying the source code, the plot of SNR vs. distance to eNB can be obtained as presented in the PhD thesis (Ikuno 2013). I will make a comparison between throughput vs. SNR as shown in the Vienna documentation (Page 23).
If it is possible, I want to understand how we can calculate the subcarrier post-equalization SNR/SINR from the Link Quality Model. To make sure my understanding, I need to check them before finding the user capacity on each sub-carrier.
1) Which parts of the Vienna simulator generate and collect these SNR/SINRs?
2) Where can we obtain the effective SINR after compression?
– (3) The wideband SINR is the ratio of the average power received from the serving cell and the average interference power received from other cells plus noise. Here the average power is the received power by considering only the macro-scopic losses. In the simulator the wideband SINR is calculated in +network_elements/UE.m denoted by the parameter obj.wideband_SINR.
– (2) The effective SINR denotes the mapped per subcarrier post-equalization SINR: Our simulator employs MIESM (Mutual Information Effective SINR Mapping). MIESM effectively averages the subcarriers in the MI (Mutual Information) domain and then remaps the average MI value to SINR. In the simulator the effective SINR is calculated in +utils/miesmAveragerFast.m.
The post-equalization SINR is calculated in +phy_modeling/post_equalization_SINR.m
