Symbols Table (Custom OFDM)
table lists the demodulated symbols and state values transmitted in the 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. burst including Preamble and Payload symbols.
Trace Color coding Scheme
A multi-color coding scheme is used to make it easy to visually identify common symbols, subcarriers, and data results within various OFDM Traces. This makes cross trace data comparisons and analysis easy to accomplish. Different colors are assigned to symbols representing a common subcarrier type including: Preamble, Pilot, Data, and Null subcarrier types. Some common color scheme Traces include: Error Vect vs. Carrier, Error Vect vs. Sym, IQ Meas, OFDM Data Burst Info, and Symbols trace data.
You can also customize and re-assign Trace colors schemes, see the Display Preferences Color tab (click tab and select a new color for the active Mod Type element).
Limiting Symbol Analysis Region
You can use the Measurement Interval and Measurement Offset properties to limit measurement analysis to a specific symbol or range of symbols > > tab).
