“…Although the BER of the Bob receiver is also slightly deteriorating with the increase of these parameters, the optimal value depends on the desired Eve BER threshold δ. In Figure 10, we show that the secrecy capacity of the proposed SPAN outperforms the artificial noise schemes in [27] [30] (referred to as SP) even without channel correlation between the main and the eavesdropper channel. At higher SNR, the difference between Bob and Eve's capacities becomes lower in the SP scheme, reaching zero when their channel is highly correlated.…”

“…At high SNR, the power allocated to AN is significantly reduced by targeting more receive antenna patterns for the GPSM system. We compare the proposed scheme with the work in [27] [30] which artificial noise has been employed to secure the PSM/GPSM transmission.…”

“…They derived asymptotic expressions for the optimal power allocation in the low and high SNR regions. The author of [30] reconstructed the zero-forcing precoder into a time-varying AN for GPSM systems to resist unknown malicious eavesdropping. They derived the BER for both the desired receiver and malicious eavesdropper under strict power constraints for the transmit signal and assumed a Rayleigh fading wiretap channel.…”

This paper proposes combined precoding and artificial noise-insertion scheme to enhance the secrecy of generalized precoded spatial modulation when the wiretap channel is partially correlated with the legitimate channel. It is shown that randomizing the modulated and spatial symbols prior to artificial noise insertion can significantly enhance secrecy even with a highly correlated eavesdropper channel. The proposed scheme exploits the channel state information (CSI) of the legitimate channel without requiring knowledge of the eavesdropper channel. The security of the proposed system depends on the amount of power allocation and the number of active receive antennas. Simulation results validate the proposed security scheme and show that the hybrid approach proposed outperforms the one that relies on artificial noise transmission.
