power_ccdf_ref()

Returns the power CCDF (Complementary Cumulative Distribution Function) curve for white gaussian noise

Syntax
ccdfRef = power_ccdf_ref(indepPowerRatioValues)

Arguments

Name	Description	Range	Type	Required
indepPowerRatioValues	power levels (in dB with respect to the average power level of a white gaussian noise signal) at which the power CCDF for white gaussian noise will be calculated	(-∞, ∞)	integer, real	yes

Examples

pCCDF = power_ccdf(T1)
ccdfRef = power_ccdf_ref( indep( pCCDF) )
where T1 is the name of a TimedSink component (in a DSP schematic), will return the power CCDF curve for white gaussian noise evaluated at the same power levels as the pCCDF curve.
ccdfRef = power_ccdf_ref( [-10::2::8] )
will return the power CCDF curve for white gaussian noise evaluated at the power levels -10, -8, -6, -4, -2, 0, 2, 4, 6, 8 (in dB with respect to the average power level of a white gaussian noise signal).

Notes/Equations

This expression can be used with input data of up to two dimensions.
The input data must be sorted in increasing or decreasing order. In addition, it is recommended that the input vector argument has uniformly spaced values. The vector "indep( X )", where X is the value returned by the power_ccdf() expression, is guaranteed to have uniformly spaced values sorted in increasing order. This would be the most typical value for the input argument of power_ccdf_ref().

A typical power CCDF measurement (see Notes/Equations for power_ccdf()) provides a reference CCDF curve along with the measured CCDF curve. This reference curve is typically the power CCDF curve for a white gaussian noise signal. This expression can generate this reference curve.
