... nr.11, RO-700506 Iasi lazara@etc.tuiasi.ro Abstract €” Turbo codes offer extraordinary performance, From the point of view of how the interleaver is especially at low signal to noise ratios, due to a low multiplicity generated, there are two major interleaver design methods: of low weight code words. The interleaver design is critical in ...
