System object: comm.gpu.ConvolutionalDeinterleaver
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) restores the original ordering of the sequence,
X, that was interleaved using a convolutional interleaver and
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 deinterleaver object uses a set of
N shift registers,
N represents the value specified by the
NumRegisters property. The object sets the delay value of the
kth 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 Nth 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.
