step
System object: comm.BCHEncoder
Package: comm
Encode data using a BCH encoder
Syntax
Y = step(H,X)
Description
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)
encodes input binary data, X
,
using a (CodewordLength
,MessageLength
)
BCH encoder with the corresponding narrow-sense generator polynomial
and returns the result in vector Y
. The input and
output length of the step function equal the values listed in the
table in Input and Output Signal Lengths in BCH and RS System Objects.
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. For more information on changing property values, see System Design in MATLAB Using System Objects.
