System object: comm.BCHEncoder
Package: comm
Encode data using a BCH encoder
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)
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, 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.
