This intense noise hinders transmitted signal and raises the error of exchanged data. Some previous works on channel coding adopt traditional codes and signal processing to solve this issue, but encountered many difficulties in handling the impulse. Regarding impulse noise, first we analyzed the impact of impulse noise to turbo code, which is a robust and popular code in white Gaussian channel. Referring to metric-erasure Viterbi algorithm, we developed a metric clipping turbo code based on partial information of impulse model. To evaluate this code in non-Gaussian channel exactly, we introduced kernel density estimation into extrinsic information transfer band chart for operating evaluation. The result of computer simulation and evaluation shows the performance is close to model-modified turbo code and the complexity is almost the same as primary turbo code. ER -
