Repeat-punctured superorthogonal convolutional turbo codes on AWGN and flat Rayleigh fading channels
South African Journal of Science, 2010 Repeat-punctured turbo codes, an extension of the conventional turbo-coding scheme, has shown a significant increase in bit-error rate performance at moderate to high signal-to-noise ratios for short frame lengths.

New High Performance Deterministic Interleavers for Turbo Codes
Advances in Electrical and Computer Engineering, 2010 Turbo codes offer extraordinary performance, especially at low signal to noise ratios, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing

ENHANCEMENT OF ITERATIVE TURBO DECODING FOR HARQ SYSTEMS [PDF]
ICTACT Journal on Communication Technology, 2016 This paper presents a new method for stopping the iterative turbo decoding. First, a bit-level convergence test using the cross-entropy analyses is used to select non converged bits and establish a simple and effective stopping rule.
