A parallel concatenated coding scheme consists of two simple constituent systematic
encoders linked by an interleaver. The input bits to the first encoder are scrambled by the …

A parallel concatenated convolutional coding scheme consists of two constituent systematic:
convolutional encoders linked by an interleaver. The information bits at the input of the first …

Serial concatenation of convolutional codes separated by an interleaver has recently been
shown, through the use of upper bounds to the maximum likelihood performance, to be …

This paper presents a new family of convolutional codes, nicknamed turbo-codes, built from
a particular concatenation of two recursive systematic codes, linked together by nonuniform …

A serially concatenated code with interleaver consists of the cascade of an outer encoder,
an interleaver permuting the outer codewords bits, and an inner encoder whose input words …

Parallel concatenated coding schemes employing convolutional codes as constituent codes
linked by an interleaver have been proposed in the literature as 'turbo codes'. They yield …

A serially concatenated code with an interleaver consists of the cascade of an outer code, an
interleaver permuting the outer codewords' bits, and an inner code whose input words are …

Turbo codes, first presented to the coding community in 1993 [1],[2], represent one of the
most important breakthroughs in coding since Ungerboeck introduced trellis codes in 1982 …

In this article, we design new turbo codes that can achieve near-Shannon-limit performance.
The design criterion for random interleavers is based on maximizing the effective free …

Concatenated coding schemes consist of the combination of two or more simple constituent
encoders and interleavers. The parallel concatenation known as" turbo code" has been …
