Block-interleaver/deinterleaver according to the IEEE 802.11-2007

Defined by two step-permutation :

The first permutation ensures that adjacent coded bits are mapped onto

nonadjacent sub-carriers. The second ensures that adjacent coded bits

are mapped alternately onto less and more significant bits of the

constellation and, thereby, long runs of low reliability (LSB) bits

are avoided.

Tested and works we-Block-interleaver/deinterleaver according to the IEEE 802.11-2007
