Abstract:

With the emergence of a large number of services in wireless communication scenarios,wireless communication is affected by various interference factors and the electromagnetic environment has become more and more complex.To solve this problem and improve the reliability of a communication system,we study the burst pulse interference environment.First,we establish a composite Poisson distribution based mixed channel of the additive white gaussian noise channel and burst erasure channel for burst pulse interference environment.Then,we study nonbinary polar codes with the multiplicative repetition spread spectrum scheme for burst pulse interference environment and propose a spread spectrum sequence selection method based on the Euclidean distance.Simulation results show that the block error rate performance and the error floor performance of the nonbinary polar codes outperform than those of binary polar codes.In addition,the proposed nonbinary polar codes with the multiplicative repetition spread spectrum scheme are better than those with the Hadamard spread spectrum scheme.

Key words: burst pulse interference, polar codes, non binary codes, multiplicative repetition spread spectrum
