Construction and Decoding of High Order Magic Square Convolutional Codes
摘要
Abstract
A high order magic square convolution code with relative greater length of information bits and constraint degrees is built based on linear block codes and convolutional codes in the paper.The analysis to the state transition is given through defining a multi-dimensional matrix, and the soft decision viterbi decoder with single structure and the ability of parallel processing is built with the help of matrix computation.The simulation and analysis demonstrate that the code has a large number of good codes with fine distance performance and high efficiency,and it has good expectations to obtain shannon codes.关键词
