Puncture

Output elements that correspond to 1s in binary puncture vector

Libraries:
Communications Toolbox / Sequence Operations

Description

The Puncture block creates an output vector by removing selected elements of the input vector and preserving others. The block determines which elements to remove and preserve by using the binary Puncture vector parameter. The block repeats the puncturing pattern, as necessary, to include all input elements. The preserved elements appear in the output vector in the same order in which they appear in the input vector.

Examples

Puncture Input Vector

Use the Puncture block to puncture an input vector by using a modulus 6 puncture pattern with 0s in the second and sixth element locations, [1;0;1;1;1;0].

Ports

Input

In — Input signal

column vector

Input signal, specified as a column vector. The input length must be an integer multiple of the Puncture vector parameter length.

Data Types: double | single
Complex Number Support: Yes

Output

Out — Output signal

column vector

Output signal, returned as a column vector. The length of the output vector is an integer multiple of the number of 1s in the Puncture vector parameter. The output signal contains only elements from the input signal that align with integer multiples of the element location of 1s in the Puncture vector.

Parameters

Puncture vector — Puncture pattern

[1 1 0 1 0 1]' (default) | column vector of binary values

Puncture pattern, specified as a column vector of binary values. The input signal length must be an integer multiple of the Puncture vector parameter length. The block repeats the puncturing pattern, as necessary, to include all input elements.

• The element locations of 0s in Puncture vector indicate which elements are removed from the input signal to construct the output signal.

• The element locations of 1s in Puncture vector indicate which elements are preserved from the input signal to construct the output signal.
