摘要

针对有限字符输入系统的无线物理层安全传输问题，提出了一种空间调制安全传输方法。该方法以信息论为基础，利用多输入多输出（MIMO

multiple-input multiple-output）系统的接收天线索引承载信息，通过切换接收天线随机化窃听者的等效信道，保证物理层安全传输。首先分析了该空间调制传输系统中合法用户和窃听者的不同接收性能。然后计算出安全传输系统的保密互信息，指出获取正的保密互信息的2个充分条件。最后给出信道互信息的估计算法，并利用有限字符集的对称性进一步降低了计算复杂度。理论分析和数据仿真验证了该安全传输方法的可行性和有效性。

Abstract

Addressing the problem of wireless physical layer security transmission for finite alphabet input systems

a spatial modulation secure transmission method is proposed.On the basis of information theory

the method utilizes the receive antenna indices of multiple-input multiple-output (MIMO) system to bear information

and randomizes the eavesdropper’s equivalent channel by switching the receive antennas

which can guarantee physical layer security transmission.First

the different receiving performances of the legitimate user and eavesdropper are analyzed in the spatial modulation secure transmission system.Second

the mutual information and secrecy mutual information of the transmission system are calculated

and two sufficient conditions that ensure positive secrecy mutual information are pointed out.Finally

an estimation algorithm of mutual information is provided.Moreover

the symmetry of finite alphabet set is exploited to decrease the computational complexity.Theoretical analysis and numerical simulation results verify the availability of the security transmission method.
