Interleaving and de-interleaving of data

This example shows how to use one of the interleaving classes.

#include <itpp/itcomm.h>
using namespace itpp;
//These lines are needed for use of cout and endl
using std::cout;
using std::endl;
int main()
{
//Declare scalars and vectors:
int rows, cols;
ivec input, output, deinterleaved;
//Declare the interleaver. The interleaver classes are templated, and therefore we must specify
//the type of the data elements. In this example we are using integers:
Block_Interleaver<int> my_interleaver;
//Initialize the interleaver class. Note that this can be done already in the declaration by writing
//Block_Interleaver<int> my_interleaver(rows,cols);
rows = 4;
cols = 5;
my_interleaver.set_rows(rows);
my_interleaver.set_cols(cols);
//Define the input to the interleaver:
input = "1:20";
//Do the interleaving:
output = my_interleaver.interleave(input);
//Do the de-interleaving:
deinterleaved = my_interleaver.deinterleave(output);
//Print the results:
cout << "input = " << input << endl;
cout << "output = " << output << endl;
cout << "deinterleaved = " << deinterleaved << endl;
//Exit program:
return 0;
}
itpp::Array
General array class.
Definition array.h:105
itcomm.h
Include file for the IT++ communications module.
itpp
itpp namespace
Definition itmex.h:37

When you run this program, the output will look like this:

input = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20]
output = [1 5 9 13 17 2 6 10 14 18 3 7 11 15 19 4 8 12 16 20]
deinterleaved = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20]
