System object: comm.PSKDemodulator
Demodulate using M-ary PSK method
Y = step(H,X)
Y = step(H,X,VAR)
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(H,X) demodulates data,
with the PSK demodulator System object,
be a scalar or a column vector with double or single precision data
type. If the value of the

8 and you set
or when you set the
DecisionMethod property to
the object accepts an input with a signed integer data type or signed
fixed point (fi objects). Depending on the
Y, can be integer or bit valued.
Y = step(H,X,VAR) uses soft decision demodulation
and noise variance
VAR. This syntax applies when
you set the
BitOutput property to true, the
Approximate log-likelihood ratio or
ratio, and the
Input port. The data type of input
be double or single precision.
obj specifies the System object on which to run this
The object performs an initialization the first time the
step method is executed. This initialization locks nontunable properties and
input specifications. For more information on changing property values, see System Design in MATLAB Using System Objects.
