About Symbol Table (LTE)

Symbol Table shows the numerical values of demodulated data (the data in the Measurement Interval) for the selected layer and can be shown as hexadecimal or binary digits.

This trace has the following characteristics:

The digits are color coded to match the channel/signal colors in Frame Summary.
The symbol locations for channel/signals that are not selected in the Composite Include list on the Profile tab will be blanked on the Symbol Table.
Signals that do not have numerical values assigned to symbol points will be shown as zeros.
Non-alloc subcarriers, when included in analysis, will be shown as zeros.
Each group of digits corresponding to a subcarrier is shown with the most significant bit first. The most significant bit is interpreted as b(i+n) where n is the highest value depending on the modulation type. For instance, b(i+5) is interpreted as the most significant bit for 64QAM modulation.

The modulation bit-mapping tables, which define b(i), are located in 3GPP TS Technical Specification 36.211 Section 7.
