Shaping EXIT Functions of Turbo Codes [PDF]
, 2008 This paper investigates the shaping of the extrinsic information transfer (EXIT) functions of parallel turbo codes, when the turbo code is used as an outer code in a serially concatenated scheme.

Coded modulation scheme employing turbo codes
Electronics Letters, 1995 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
Journal of Engineering, 2003 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.
