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.

On List Sequence Turbo Decoding

IEEE Transactions on Communications, 2005
An algorithm for decoding Turbo codes that combines conventional Turbo decoding and list sequence maximum a posteriori probability decoding is presented and evaluated. Compared to previous results on this theme, performance improvements in the order of 0.7 dB are obtained for Turbo codes with 514-b pseudorandom interleaving at a frame error rate of 10 ...

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.
