ccdf
Description
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 jth channel is above its
average signal power by relpower
(i,j), in dB, is
prob
(i)/100.
Data Types: double
Version History
Introduced in R2022a
