Threshold Reference (Channel Sounding)
specifies the reference for the RMS Delay Spread threshold. The actual value of the threshold (Threshold Reference + Threshold Offset) is shown in the RMS Dly Spr Thresh (dBm) metric.
- Relative to the power level which corresponds to 3x the standard deviation of the noise. The idea is to include as many paths as possible without including a significant amount of peaks from noise.
- Relative to the peak of the impulse response. This is the method used in ITU International Telecommunications Union: A United Nations agency that deals with telecommunications issues.-R P.1407-8.
