Turbo-decoder quantization for UMTS

IEEE Communications Letters, 2001
The use of turbo codes is proposed for high-rate data services in third generation wireless communication systems. Bit-true models are mandatory for hardware and software implementations. In this paper we present to the best of our knowledge the first investigation of a combined bit-width optimization of input data and internal data for an 8-state ...

Turbo decoding of quantized data

IEEE Transactions on Communications, 2002
Much of the work on turbo decoding assumes that the decoder has access to infinitely soft (unquantized) channel data. In practice, however, a quantizer is used at the receiver and the turbo decoder must operate on finite precision, quantized data. Hence, the maximum a posteriori (MAP) component decoder which was designed assuming infinitely soft data ...

Quantization issues in turbo decoding

Proceedings. 2005 International Conference on Communications, Circuits and Systems, 2005., 2005
It is necessary to quantize the variables in VLSI implementation of a turbo decoder. When the quantile interval of received symbol sequence (RSS) is fixed, the required precision of state metrics, log-likelihood ratio, etc are limited by the RSS quantizing error propagation.

Improved performance SOVA turbo decoder

IEE Proceedings - Communications, 2006
A novel approach for improving the performance of the soft-output Viterbi algorithm (SOVA) when applied to turbo decoding is proposed. Based upon a modified two-step scaling factor approach for the decoder's extrinsic information, it is shown that the proposed technique reduces significantly the error floor present in previous SOVA-based turbo decoding

Turbo Decoder with Parallel Processing

2013
The operating frequency \(\mathcal{F}\) is the decisive factor in throughput calculation of conventional turbo decoders. Although the modification to circuits can improve this factor, there is a limit to the critical path delay, and it is difficult to supply a stable clock signal with high frequency.
