“…where f r,e (γ x,r , γ x,e ) is the joint PDF of the SIR at the receiver and the eavesdropper. Performance studies of PLS with CSI imperfections due to estimation errors at the receiver and/or limited feedback can be found in [42], [43] and references therein. Studying the impact of imperfections on the performance comparison with and without boundaries is a topic for future work.…”

In this paper, we study the receiver performance with physical layer security in a Poisson field of interferers. We compare the performance in two deployment scenarios: (i) the receiver is located at the corner of a quadrant, (ii) the receiver is located in the infinite plane. When the channel state information (CSI) of the eavesdropper is not available at the transmitter, we calculate the probability of secure connectivity using the Wyner coding scheme, and we show that hiding the receiver at the corner is beneficial at high rates of the transmitted codewords and detrimental at low transmission rates. When the CSI is available, we show that the average secrecy capacity is higher when the receiver is located at the corner, even if the intensity of interferers in this case is four times higher than the intensity of interferers in the bulk. Therefore boundaries can also be used as a secrecy enhancement technique for high data rate applications.

“…Among these works, [17]- [21] examined the case when the uncertainty is the result of an error of estimation, and [22]- [24] analyzed the wiretap channel with outdated CSI. A synopsis of how different levels of CSIT impact the system's security is provided in [25] and a detailed state-of-the-art review of physical layer security with CSIT uncertainty is presented in [26].…”

“…Since SU is allowed to share the spectrum with PU, security issue in such networks becomes more complex [11], [12], [13]. The physical layer security technique can provide secure communication through time-variability of wireless channel without secret key [14]. It can greatly improve the security of wireless communication system both in theory and in practical engineering applications [15].…”
