ccdf

Get coordinates of CCDF curves

Since R2022a

Syntax

[relpower,prob] = ccdf(meter)

Description

[relpower,prob] = ccdf(meter) returns the coordinates of the CCDF curves.

Examples

Plot Coordinates of CCDF Curves

Compute the average power measurement of the generated voltage signal.

x = complex(rand(15000,1)-0.2,rand(15000,1)-0.2);
pm = powermeter(ComputeCCDF=true);
averagePower = pm(x);                            % power in dB

Plot the computed coordinates of the CCDF curve.

[relpower,prob] = ccdf(pm);
semilogy(relpower,prob)
xlabel('Relative Power (dB)');
ylabel('Probability (%)');
ylim([0 125]);
grid on;
title('CCDF Measurement');

Input Arguments

meter — Power meter

powermeter system object

Power meter, specified as a powermeter System object™.

Output Arguments

relpower — Relative power

N-by-M matrix

Relative power in dB, returned as an N-by-M matrix. M equals the number of columns in the signals provided and N equals ceil(PowerRange/PowerResolution) + 1.

Data Types: double

prob — Probability

matrix

Probability in percentage, returned as a matrix. The probability that the instantaneous signal power of the j^th channel is above its average signal power by relpower(i,j), in dB, is prob(i)/100.

Data Types: double
