System object: comm.CoarseFrequencyCompensator
Package: comm
Compensate for frequency offset
Y = step(CFC,X)
[Y,EST] = step(CFC,X)
Note
Starting in R2016b, instead of using the step
method
to perform the operation defined by the System object™, you can
call the object with arguments, as if it were a function. For example, y
= step(obj,x)
and y = obj(x)
perform
equivalent operations.
Y = step(CFC,X)
compensates for the carrier
frequency offset of the input X
and returns the
result in Y
. X
must be
a column vector. The step method outputs the compensated signal Y
as
a complex column vector having the same dimensions and data type as X
.
[Y,EST] = step(CFC,X)
returns a scalar
estimate of the frequency offset, EST
.
Note
CFC
specifies the System object on
which to run this step
method.
The object performs an initialization the first time the step
method
is executed. This initialization locks nontunable
properties and input specifications, such as dimensions, complexity,
and data type of the input data. If you change a nontunable property
or an input specification, the System object issues an error.
To change nontunable properties or inputs, you must first call the release
method
to unlock the object.
