I’m using the last version of LTE system level …how can specify the type of modulation or the order also how can I set up for example 64QAM or 16QAM ?? please even the members if you know that tell me please
The modulation order is chosed by the Channel Quality Indicator (CQI). The system-level simulator uses a SNR to CQI mapping. The values of CQI are generated from the feedback loop. If you want a specific modulation then you have to fix the CQI to the corresponding value.
thank you for your reply …
i have another query if you could to help me…. i have used the carrier frequency (5GHz) but the throughput didn’t increase…my question why the throughput didn’t increase with increasing of carrier frequency?
If you keep the same bandwidth then you will not see much differences, but please be careful which pathloss model are you ussing with the carrier frequency of 5GHz. There are different path-loss models for different frequency ranges.
