OFDM Eq MIMO Cond Number (Custom OFDM)
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. Eq MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. Cond Number is only available for multiple channel measurements.
trace result is a vector containing the "condition number" of the equalizer channel frequency response matrices, one condition number value for each subcarrier. Condition number is a standard measure of how ill-conditioned a matrix is.
Condition number is defined as the ratio of the maximum singular value to the minimum singular value of a matrix. The value is always real, and always greater than or equal to one. Larger values indicate a more ill-conditioned matrix. If the condition number is larger than the SNR Signal-to-Noise Ratio of the signal, it is likely that MIMO separation of the multiple data streams will not work correctly.
This result is computed only when there are multiple data streams present.
When there is only one input channel, or when the input channels contain only one data stream, the trace is blanked and a "NO DATA" trace LED is displayed.
