Irregular Vector Turbo Codes with low complexity
The term Block Turbo Code typically refers to the iterative decoding of a serially concatenated two-dimensional systematic block code. This paper introduces a Vector Turbo Code that is irregular but with code rates comparable to those of a Block Turbo ...

BIT ERROR OPTIMIZATION OF CODED OFDM SYSTEM OVER RAYLEIGH FADING CHANNEL [PDF]
Low Density Parity-Check (LDPC) codes are one of the hottest topics in coding theory today. This code invented in the early 1960's, and it having an amazing comeback in the last few years.

Coded modulation scheme employing turbo codes
The authors present a turbo coding scheme for bandwidth-efficient modulation that outperforms turbo coding with Gray mapping by employing Ungerboeck codes as component codes. The scheme can be decoded iteratively and achieves very good bit error rates at low signal to noise ratios after a small number of iterations. 8PSK is used as an example, although

THE EFFECT OF TRELLIS TERMINATION ON THE PERFORMANCE OF TURBO CODE
This paper introduces a new class of convolutional codes, which is called Turbo Code. Turbo Code was shown to achieve performance in terms of Bit-Error-Rate (BER), which is near Shannon limit.
