Package: comm
Measure complementary cumulative distribution function
The CCDF
object measures the probability of
a signal's instantaneous power to be a specified level above its average
power.
To measure complementary cumulative distribution of a signal:
Define and set up your CCDF object. See Construction .
Call step
to measure complementary cumulative
distribution according to the properties of comm.CCDF
.
The behavior of step
is specific to each object in
the toolbox.
H = comm.CCDF
creates a complementary cumulative
distribution function measurement (CCDF) System object™, H
,
that measures the probability of a signal's instantaneous power to
be a specified level above its average power.
H = comm.CCDF(

a CCDF object, Name
,Value
)H
, with each specified property
set to the specified value. You can specify additional namevalue
pair arguments in any order as (Name1
,Value1
,...,NameN
,ValueN
).

Number of CCDF points Specify the number of CCDF points that the object calculates.
This property requires a numeric, positive, integer scalar. The default
is 

Maximum expected input signal power Specify the maximum expected input signal power limit for each
input channel. The default is 

Power units Specify the power measurement units as one of
