Résumé :
[en] Interference usually is an adverse phenomenon in wireless
networks. However, the interference can potentially be used to boost
the secrecy rate in wireless interference channels. This work studies
the secrecy rate in a two-user interference network where unintended
user may overhear one of the users, namely user 1. User 1 tunes its
transmission power in order to maximize its secrecy rate as well as to
maintain the quality of service at the other user’s destination, user 2,
while both user’s power limits are considered. It is demonstrated that
achieving a positive secrecy rate for user 1 only depends on the channel
conditions and user 2’s transmission power. Consequently, depending on
the channel conditions, the exact threshold for user 2’s transmission power
which leads to a positive secrecy rate for user 1 is derived.
