System object: comm.DifferentialDecoder
Package: comm
Decode binary signal using differential decoding
Y = step(H,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(H,X) decodes the differentially
encoded input data, X, and returns the decoded
data, Y. The input X must be
a column vector of data type logical, numeric, or fixed-point (embedded.fi
objects). Y has the same data type as X.
The object treats non-binary inputs as binary signals. The object
computes the initial output value by performing an Xor operation of
the value in the InitialCondition property and the
first element of the vector you input the first time you call the
step method.
Note
obj 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.
