Encode data using a BCH encoder


Y = step(H,X)



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.


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.
