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
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
release method to unlock the object.
