Nonlinear Phenomena in the Turbo Decoding Algorithm

چکیده
In this paper, we treat the turbo decoding algorithm as a dynamical system parameterized by a single parameter that closely approximates the signal-to-noise ratio (SNR). A whole range of phenomena known to occur in nonlinear systems, like the existence of multiple fixed points, oscillatory behavior, bifurcations, chaos and transient chaos are found in the turbo decoding algorithm.

Bifurcations and Chaos in Turbo Decoding Algorithms
The turbo decoding algorithm is a high-dimensional dynamical system parameterized by a large number of parameters (for a practical realization the turbo decoding algorithm has more than 10 variables and is parameterized by more than 10 parameters). In this chapter we treat the turbo decoding algorithm as a dynamical system parameterized by a single parameter that closely approximates the signal...
متن کاملApplications of nonlinear dynamics to the turbo decoding algorithm
In this paper, we treat the turbo decoding algorithm as a dynamical system parameterized by the SNR (signal-to-noise ratio). A whole range of nonlinear phenomena, including chaos and transient chaos, have been shown to occur in the turbo decoding algorithm. As an application, we develop an adaptive technique to control transient chaos, leading to an improvement of the BER (bit error rate) perfo...

متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...
