Design and simulation of punctured woven convolutional codes

Le résumé fourni par la source

Woven convolutional codes is a novel class error-correcting codes with high compatibility. But the coding efficiency of WCCs is lower and decoding delay is higher. The hardware realization is difficult for its encoding structure characteristic. These flaws restrict the applications of WCCs. In this paper, the puncturing technology is employed to enhance the coding efficiency and promote the application of WCCs. The puncturing technology is used to punctured outer warp and inner warp at first respectively. Over AWGN channel simulations show that the performance of punctured WCCs with outer warp is better than the non-punctured WCCs with outer warp with same rate and same number of outer encoders, and the complexity of encoding and decoding for WCCs based on puncturing is reduced greatly and the coding efficiency is improved greatly.
