This paper considers the secrecy performance of several schemes for
multi-antenna transmission to single-antenna users with full-duplex (FD)
capability against randomly distributed single-antenna eavesdroppers (EDs).
These schemes and related scenarios include transmit antenna selection (TAS),
transmit antenna beamforming (TAB), artificial noise (AN) from the transmitter,
user selection based their distances to the transmitter, and colluding and
non-colluding EDs. The locations of randomly distributed EDs and users are
assumed to be distributed as Poisson Point Process (PPP). We derive closed form
expressions for the secrecy outage probabilities (SOP) of all these schemes and
scenarios. The derived expressions are useful to reveal the impacts of various
environmental parameters and user's choices on the SOP, and hence useful for
network design purposes. Examples of such numerical results are discussed.
