On allocation of turbo decoder iterations

14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004
The computational requirements of turbo decoders are heavy and depend on the number of decoding iterations. However, only a few iterations are often enough for obtaining an error free outcome. Instead of idling during the unused iterations, the released time slots can be used for enabling extra iterations required by the decoding, when the errors are ...

Energy-efficient turbo decoder

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
Turbo codes have been recently adopted in the next generation of wideband CDMA standards. These codes achieve superior performance at the expense of high computational complexity. This makes their low energy implementation a very important yet challenging problem.

Turbo decoding for generalized channels

IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
We propose a turbo decoding framework in the presence of insertions and deletions as well as substitutions in the received sequence. The decoding algorithm is based on the Viterbi algorithm for this special channel. The synchronization information is exchanged between decoders in the proposed structure and extrinsic information is used, as is commonly ...

Parallel Decoding of Turbo Codes

2018
Given a turbo code generated by parallelly concatenated recursive systematic convolutional encoders, the turbo decoder comprises MAP decoders coupled in a serial connection, where each MAP decoder decodes a recursive systematic convolutional code. We propose a turbo decoding algorithm that, on a logical level of abstraction, is made of several turbo ...

Stochastic models for turbo decoding

IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005
This paper proposes a stochastic framework for modelling and analysis of turbo decoding. By modelling the input and output signals of a turbo decoder as random processes, we prove that these signals become ergodic when the code block size becomes very large.
