Novel block convolutional code

A novel block convolutional code was designed for error control of fixes-length message.It has the advantages of pure block codes and convolutional code,with high transmission efficiency,low delay and high performance.First the basic idea of block convolutional code was introduced,and then generic matrix and check matrix as well as an application example were presented.The whole encoding and decoding process were also demonstrated by an example.The transmission efficiency and bit error rate(BER) performance were analyzed subsequently.Finally,the BER performances of block convolutional code and existing convolutional code were compared by computer simulation.The simulation result shows that,compared with existing convolutional code,block convolution code has higher transmisson effieiency and similar BER performance.
