System object: comm.ConvolutionalInterleaver
Permute input symbols using shift registers
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) permutes input sequence,
X, and returns
Y. The input
X must be a
column vector. The data type can be numeric, logical, or fixed-point (fi objects).
Y has the same data type as
convolutional interleaver object uses a set of N shift registers,
where N is the value specified by the NumRegisters property. The
object sets the delay value of the k-th shift register to the product
of (k-1) and the RegisterLengthStep
property value. With each new input symbol, a commutator switches to a new register and
the new symbol shifts in while the oldest symbol in that register shifts out. When the
commutator reaches the N-th register and the next new input occurs ,
it returns to the first register.
obj specifies the System object on which to run this
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.
