Blind Recognition of (n,1,m) Recursive System Convolutional Code
摘要
Abstract
Recursive system convolutional code( RSC code) is the commonly used encoding form of Turbo sub-encoders. For the blind recognition problem of (n,1,m) RSC code,a method based on Walsh-Had-amard transform is proposed. Firstly,code parameters are estimated by analyzing matrix constructed by the received codeword. Then,the mathematical recognition model is derived according to RSC code’s charac-teristics,the specific implementation steps are provided and the principle of the method is introduced. The simulation results from Matlab show that the performance of the method is obviously more excellent in com-parison with other methods. The recognition probability reaches 90% when bit error rate( BER) is as high as 10-2 ,which indicates the great significance of the proposed method for further research on Turbo code.关键词
