摘要：
Performance of turbo codes over an impulsive noise channel is analyzed by extending an evaluation method over AWGN channels. Burst noise generation is considered with respect to the noise model by applying a hidden Markov model (HMM). A bound calculation method is derived by using a combined trellis which consists of code trellis and HMM trellis. In the simulation, an iterative decoder using the combined trellis into each component decoder is proposed. By using this method, the simulation results show the expectation of the coincidence with the calculated bounds at larger E-b/N-0 for various conditions. Search results of optimum component code using proposed bound are shown.
