mmwave Question about variables

[tonya...@gmail.com]

Hi,

I'm using mmwave module but I came across something unusual in mmwave-amc-test.cc script.

The names of the variables suggest that these are SNR values in dB, but the comments are indicating that these are, in fact, distances in meters?

double snrIncDb = 0.1; // increment by 10 meters
double snrMinDb = -7.0; // eNB-UE distance in meters
double snrMaxDb = 30; // eNB-UE distance in meters

also, later on, there is a line:

uePositionAlloc->Add (Vector (snrMinDb, 0.0, 0.0));

which also suggest that snrMinDb is the distance in meters actually?

Could someone please clarify this for me?

BR,

Tonya

Also,

this script gives an output in which mentioned variables are treated as SINR, meaning snrInit will be changing by 0.1 (snrIncDb) from -7 (snrMinDb) to 30 (snrMaxDb)  

	std::cout << "************* SINR changing to " << snrInit << " (MCS = " << mcs << " ) *************" << std::endl;
	Simulator::Schedule (MicroSeconds(3*100), &MmWaveSpectrumPhy::UpdateSinrPerceived,
	enbDev->GetPhy()->GetDlSpectrumPhy (), specVals);
	//enbPhy->GenerateDataCqiReport(specVals);
	if (snrInit > snrMaxDb)
	{
	return;
	}
	Simulator::Schedule (MilliSeconds(snrUpdateIntervalMs), &updateSnr, snrInit+0.1, enbDev, model, amc);
	}
	int

Hi Tonya,

the mmWave module is not part of the ns-3 official codebase.

Therefore, I would recommend to send your questions directly to the developers/maintainers of that module

Thank you for your response Konstantinos. 

Yes, I'm aware that the code is unofficial, but I eas hoping someone could help. 

I'll wait for authors' to respond.
