- Abstract
- In this paper, an optimal power allocation between
information and jamming signals at a secondary user (SU) in
cognitive radio is investigated. The power allocation is achieved
to minimize SU’s outage probability while keeping a secrecy
requirement at a primary user (PU). By sending jamming signals,
SU contributes to improving PU’s secrecy outage, which in
turn enables SU to find a vacant room of radio spectrum for
transmitting its own information signal. The jamming signal is
assumed to be known to PU in advance. But we investigate both
of two cases regarding whether SU’s receiver knows the jamming
signal or not. SU’s outage probability is derived as a function of
the power allocation for the respective cases and is optimized with
the primary secrecy constraint. Numerical results are provided to
verify the analysis and to give insights on the outage performance
of SU.
