2.7 The Interleaver

The interleaver c02-math-0861 bijectively maps the binary codewords c02-math-0862 into the codewords c02-math-0863. The interleaver is determined by the interleaving vector c02-math-0864 which defines the mapping between c02-math-0865 and c02-math-0866 as follows:

2.99 equation

where c02-math-0868 (see (2.80)) and

2.100 equation

The sequences c02-math-0870 and c02-math-0871 are obtained, respectively, by reading columnwise the elements of the sequences of binary vectors and . Very often, we will skip the notation ...
