MIMO Common Tracking Error (NB-IoT)
antenna detection threshold topic for more information.
shows the common tracking error data for all paths, whether detected or not. See theSee the non-MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. Common Tracking Error trace topic for more information.
OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. symbol FFT Fast Fourier Transform: A mathematical operation performed on a time-domain signal to yield the individual spectral components that constitute the signal. See Spectrum. taken from the center of the cyclic prefix. This is different from most Demod Trace Data and Layer Trace Data (including the non-MIMO Common Tracking Error trace) which use the Symbol Timing Adjust parameter to determine the location of the symbol FFT.
trace data is always calculated from anSee Also
