Turbo STFC decoding with the Zero Forcing decoder
IEEE Africon '11, 2011In this paper, a method for the joint decoding of a MIMO system using apriori information in conjunction with the Zero-Forcing decoder is presented. The proposed method is compared with an existing method based on receive vector translation. It is shown that both methods perform similarly in the case of the Zero-Forcing decoder.

Stochastic models for turbo decoding
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005This 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.

A Low-Complexity Scheduling for Turbo Equalization with Turbo Decoding
2007 IEEE 65th Vehicular Technology Conference - VTC2007-Spring, 2007A novel scheduling for turbo equalization with turbo decoding is proposed. The use of turbo codes associated to turbo equalizers has been frequently investigated in the literature. The conventional turbo equalizer with turbo decoding consists of a soft input soft output equalizer cooperating with a turbo decoder. In this way, the turbo decoder performs

Improvements in Turbo Decoding
IETE Journal of Research, 2002In recent years iterative concatenated decoding has regained popularity starting with the remarkable results presented in a paper by a group of French researchers. They introduced a new family of convolutional codes, nicknamed "Turbo codes" due to its resemblance with the turbo engine.

Turbo decoding on tailored OpenCL processor
2013 9th International Wireless Communications and Mobile Computing Conference (IWCMC), 2013Turbo coding is commonly used in the current wireless standards such as 3G and 4G. However, due to the high computational requirements, its software-defined implementation is challenging. This paper proposes a static multi-issue exposed datapath processor design tailored for turbo decoding.

Reconfigurable turbo decoding for 3G applications
Signal Processing, 2004Software radio and reconfigurable systems represent reconfigurable functionalities of the radio interface. Considering turbo decoding function in battery-powered devices like 3GPP mobile terminals, it would be desirable to choose the optimum decoding algorithm: SOVA in terms of latency, and log-MAP in terms of performance.

Interleaver for High Parallelizable Turbo Decoder
2007In this paper a new interleaver is proposed as turbo codes intern interleaver. This interleaver designed from shifted identity matrices has been developed to facilitate implementation of parallelized turbo decoding. The structure is first illustrated and then, implementation aspects are discussed.

The memory requirement for the uniform quantization turbo decoder is very large. The nonuniform quantization provides better or identical performance than the uniform scheme. But it is inconvenient for the latter to implement with the hardware circuits.

Recently, turbo code has gathered much attention for its outstanding performance. Many literatures have been published on algorithm and applications of turbo code. However, there is little progress on the decoding mechanism of turbo decoder. In this paper we propose an asymmetry AWGN (additive white Gaussian noise channel) model.

Parallel Decoding of Turbo Codes
2018Given 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 ...
