为了解决无线通信中常见的突发误码问题，提出了一种新的抗突发误码的Turbo码设计方案。该设计方案通过采用双重交织结构，极大地降低了突发误码对接收信息序列连续删除的风险，在不引入额外延迟的前提下，显著地提升了Turbo码抗突发误码的性能。仿真结果表明，当通信中存在较长突发误码时，双重交织Turbo码比一般Turbo码的纠错性能更好，其误比特率甚至可达到10-6数量级。

A new Turbo code design is proposed to solve the problem of the burst error which commonly ap-pears in wireless communications. The design uses the dual interleaving structure,which can greatly reduce the risk of the received information bits being erased in series caused by the burst error. As a result,the new Turbo code can achieve much improvement of correcting burst errors without additional delay. Simula-tion results show that the dual interleaving Turbo code has better error correcting performance than the commom Turbo code and the bit error rate can even reach 10-6 orders of magnitude.
