Low-SNR Analysis of Interference Channels under Secrecy Constraints
In this paper, we study the secrecy rates over weak Gaussian interference
channels for different transmission schemes. We focus on the low-SNR regime and
obtain the minimum bit energy E_b/N_0_min values, and the wideband slope
regions for both TDMA and multiplexed transmission schemes. We show that
secrecy constraints introduce a penalty in both the minimum bit energy and the
slope regions. Additionally, we identify under what conditions TDMA or
multiplexed transmission is optimal. Finally, we show that TDMA is more likely
to be optimal in the presence of secrecy constraints
Low-SNR Analysis of Interference Channels under Secrecy Constraints
Abstract β In this paper, we study the secrecy rates over weak Gaussian interference channels for different transmission schemes. We focus on the low-SNR regime and obtain the minimum bit energy Eb values, and the wideband slope regions N0 min for both TDMA and multiplexed transmission schemes. We show that secrecy constraints introduce a penalty in both the minimum bit energy and the slope regions. Additionally, we identify under what conditions TDMA or multiplexed transmission is optimal. Finally, we show that TDMA is more likely to be optimal in the presence of secrecy constraints. I
