Algorithm of Prediction Control Based on Time Series Analysis
Abstract：In the analysis of Turbo codes decoding structure and transmission characteristics of exterior information,based on the time series and then from the point of view of an exterior decoder component of the transmission of information laws,an improved iterative decoding structure based on prediction algorithm is presented.The n-order polynomial linear model of the component decoder is established,and the values of the former n-iterations exterior information is saved in to the linear model.The polynomial fitting curve or the index component algorithm is adopted to predict the(n+1) iterative exterior information.The value of predicted exterior information is taken instead of the(n+1) iterative exterior information.Under the premise of accurately predict the exterior information and the closely bit error rate performance,it simplifies the decoding structure and reduces the number of iterations and iteration delay.
