Propagation Model Hybrid Building Propagationloss Model Itu 1411Itu

• Propagation Model : Hybrid. Building. Propagationloss. Model • Itu 1411/Itu 1238 ( depending on indoor / outdoor/ distance<1000) • The path loss models are manually verified and produce correct results • The point to mention is that the result of Sinr that determines the MCS/CQI (either using Piro/MIerror. Model) show be same as that is produced by REM plots, where as it differs • All the parameters are kept DEFAULT with a clean NS 3 -3. 14 install • Only the following changes are made to see clear results -Position Allocation is changed to constant position instead of random -Only kept one Txnode and one UE to avoid the effect of interference -Increase the attribute of REMhelper, -> resolution x/y to grab the exact values at desired coordinates

Case 1: Home. Enb (0, 0) – UE (30, 0) Home. Node- Tx Power 17 d. Bm REM Maps: Sinr : 12. 05 d. B (10 log(16. 05)) EPC: Sinr : 42. 1635 d. B MCS: 28

Case 2: Home. Enb (0, 0) – UE (100, 0) REM Maps: Sinr : -19. 80 d. B (10 Log(0. 104)) EPC: Sinr : 21. 2484 d. B MCS: 24

Case 3: Enb (0, 0) – UE (500, 0) Case 4: Enb (0, 0) – UE (2000, 0) Manual calculations for another case has been attached as PDF, The case is for 30 m user-Txnode distance. The user & Home. Enode. B are in the same appt & same room. The path loss & shadowing is verified (ITU-1238) , where as the problem seems to be at the calculation of RXPSD. I can provide further details if required.
