In this chapter, we discuss the physical layer secrecy transmission in a downlink cellular network under TDMA, coexisting with randomly located eavesdroppers. We adopt and investigate a secure multi-antenna transmission scheme in which artificial noise is injected into the null space of the legitimate channel to confuse eavesdroppers, and provide a comprehensive secrecy performance analysis and system design/optimization under the stochastic geometry framework. We first analyze the optimal power allocation to minimize the SOP. Subject to an SOP constraint, we then propose a dynamic parameter transmission scheme (DPTS) and a static parameter transmission scheme (SPTS) to maximize secrecy throughput. Our results give new insight into secure transmission designs in a random cellular network. Numerical results are demonstrated to validate our theoretical analysis.
