In this paper, a secure generalised precoding aided quadrature spatial modulation (SGPQSM) scheme is proposed to resist the passive eavesdropping that is unknown to the transmitter. With the help of artificial noise in the null space, the SGPQSM scheme can retain all the advantages of generalised precoding aided quadrature spatial modulation (GPQSM) at the legitimate receiver while producing interference to the eavesdropper. Signal space diversity (SSD) is also used to increase the "diversity order". Then the secrecy capacity of our proposed SGPQSM is analyzed and the optimal power allocation between signal and artificial noise is investigated. Simulation results demonstrate that our SGPQSM can significantly improve the secrecy performance. In multiple-input multiple-output systems, the proposed SGPQSM scheme performs better than the existing secure scheme.
