Available Trace Data (NB-IoT)

The NB-IoT traces contain information about demodulation results.

• MIMO trace data contain information about all NRS/Rx antenna port paths. This includes equalizer frequency response, equalizer impulse, and the MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. info table.

• Demod trace data provide demodulation results that are not specific to a particular layer. This includes equalizer frequency response, equalizer impulse response, and EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. minimization and tracking information.

• Layer trace data contain downlink demodulation results that are specific to a particular layer trace. This includes error vector traces, IQ traces, resource block traces, and the detected allocations trace.

• Channel trace data provide pre-demod information about each of the measurement channels. This includes time traces, spectrum traces, calibration corrections, and statistical traces (PDF 1) Probability Density Function Trace Data, or 2) Portable Document Format (PDF) created by Adobe Systems is an open standard for document exchange., CDF Cumulative Distribution Function: The cumulative probability that a parameter will be less than a given value X., CCDF Complementary Cumulative Distribution Function).
