comm.QPSKModulator
Modulate using QPSK method
Description
The comm.QPSKModulator
object modulates a signal using the quadrature phase
shift keying (QPSK) method. The output is a baseband representation of the modulated
signal.
To modulate using the QPSK method:
Create the
comm.QPSKModulator
object and set its properties.Call the object with arguments, as if it were a function.

Creation
Syntax
Description
qpskmod = comm.QPSKModulator
creates a System object™ to modulate input signals using the QPSK method.
qpskmod = comm.QPSKModulator(
sets properties using one or more name-value arguments. For example,
Name
,Value
)'OutputDataType'='single'
specifies output of the modulated signal
values in single precision data type.
qpskmod = comm.QPSKModulator(phase,
sets the Name
,Value
)PhaseOffset
property to
phase
and optional name-value arguments. Specify
phase
in radians.

Object Functions
To use an object function, specify the
System object as the first input argument. For
example, to release system resources of a System object named obj
, use
this syntax:
release(obj)
