摘　　要：在分析信道编码和信息隐藏技术相结合的基础上,提出了Alamouti编码多天线系统中的基于LDPC码的信息隐藏方案,理论推导了单天线编码信道及多天线编码信道系统中的信息隐藏容量上限,并进行数值验算和MAT-LAB仿真验证。实验结果表明,较之单天线编码信道,基于多天线编码信道的信息隐藏容量有明显的提高。Based on analysis of the combination between channel coding technologies and information hiding technologies,an information hiding scheme based on LDPC codes is proposed,which is implemented in Alamouti coding MIMO system.A theoretical analysis about information hiding capacities of the coding channel system and multi-antennas coding channel system is presented.Then,it evaluates the proposed scheme by numerical analyses and MATLAB simulations.Compared with the single antenna channel coding system experimental results show that the information hiding capacity based on multiple antenna channel coding system is improved significant.
