Signal amplifiers

In this paper, the performance of a multisource half-duplex relaying network utilizing the time-switching approach is investigated. Particularly, the relay simply relies on the harvested energy from the selected source to perform its operations such as amplifying and forwarding the source signals.

In this paper, an approach method to improve secrecy cooperation transmissions using combined signals is investigated in which data and jamming signals are combined at a source node based on power allocation strategy. The secrecy system performances are evaluated using asymptotic secrecy outage probabilities of end-to-end achievable secrecy rates over flat and block Rayleigh fading channels.
