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,
X, with the
GPU PSK Demodulator
H, and returns
X must be a scalar or a column vector with double- or single-
precision data type. Depending on the BitOutput property
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 DecisionMethod property
Approximate log-likelihood ratio or
ratio, and the VarianceSource property
Input port. The data type of input
be double or single precision.
obj specifies the System
which to run this
The object performs an initialization the first time the
is executed. This initialization locks nontunable
properties (MATLAB) 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
release method to unlock the object.
