This letter designs a robust beamformer for correlated multiple-input-single-output wiretap channels with multiple noncollaborating passive single-antenna eavesdroppers under channel uncertainty. Assuming that the source has only partial main channel information and statistical wiretap channel information, we seek to maximize the secrecy rate under the transmit power and secrecy outage constraints. To enhance security, the correlation between the main and wiretap channels, as a resource, is fully utilized to optimize the secure beamformer. Simulation results show that the secrecy rate is improved significantly under the transmit power and secrecy outage constraints.
