摘要： 针对直接序列扩频系统伪随机(Pseudo Noise,PN)码资源有限且码索引调制系统误码率性能下降的问题,提出了一种基于可逆的初等元胞自动机加密的扩展码索引调制方案。首先,针对PN码资源有限的问题,提出使用混沌规则的初等元胞自动机对PN码进行迭代的方案,从而实现扩展PN码的目的;其次,针对码索引调制误码率性能下降的问题,提出了一种可逆元胞自动机加密的码索引调制方案,在发射端,把信息比特切割成调制比特和映射比特,并分别映射为调制符号和扩频码索引,使用对应索引的扩频码对同相分量进行扩频,同时使用可逆元胞自动机对映射比特进行加密,加密后的映射比特为调制符号的正交分量选取对应索引的扩频码进行扩频。仿真与分析结果表明,在相同频谱效率条件下,在加性高斯白噪声信道中,当误码率为10－5时,扩展码索引调制方案的误码率性能优于码索引调制和广义码索引调制方案约2~4 dB,优于非正交码移键控码索引调制方案约0.5 dB。

Abstract: In order to address the problems of limited pseudo noise(PN)code resources in direct sequence spread spectrum system and degraded bit error rate(BER)performance of code index mo-dulation system,this paper proposes an extended code index modulation(E-CIM)scheme based on reversible elementary cellular automata encryption.First,to address the problem of limited PN code resources,a method of iterating PN codes using chaotic rules of elementary cellular automata is proposed to achieve the purpose of extending PN codes.In addition,to address the problem of BER degradation of code index modulation,this paper proposes a code index modulation scheme with reversible elementary cellular automata encryption,in which the information bits are cut into modulation bits and mapping bits at the transmitter side,and mapped into modulation symbols and spreading code indexes,respectively.The in-phase component is spread using the spreading code of the corresponding index,while the mapped bits are encrypted using the reversible elementary cellular automata,The orthogonal component is spread by the spreading code corresponding to the index selected by the encrypted mapped bits.Simulation and analysis results show that under the same spectrum efficiency conditions,the BER performance of E-CIM is superior to that of the CIM and GCIM schemes by about 2~4 dB and superior to that of the N-CSK-CIM scheme by about 0.5dB in an additive Gaussian white noise channel when the BER is 10－5.

Key words: Direct sequence spread spectrum, Code index modulation, Elementary cellular automata, Bit error rate
