Abstract

A directional modulation (DM) aided secure spatial modulation (SM) scheme is proposed, which amalgamates the security of DM and high efficiency of SM, capable of achieving physical layer security (PLS) communications for SM. The principle of the proposed DM aided secure SM scheme is analyzed. Besides, the optimal maximum likelihood (ML) detector and a low-complexity near-ML (NML) detector are given for the receiver in the desired direction, respectively. Simulation results demonstrate that 1) the proposed DM aided secure SM scheme exhibits excellent BER performance at the desired receiver while the BER worsens at undesired receivers and 2) the NML detector reduces detecting complexity greatly with only 1dB SNR penalty compared with the optional ML detector.
