Error Vect vs. Carrier (Sym overlay) (Custom OFDM)
trace shows the value of the error vector for each point 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. time-frequency grid. The value shown is usually 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., but you can also choose other Trace Formats.
This trace contains the same data as the Error Vect vs. Sym (Carrier overlay) trace, except that the data is viewed with subcarriers on the x-axis and OFDM symbols on the z-axis (overlay axis). See the Error Vect vs. Sym (Carrier overlay) topic for more information.
