In this paper, a signal-based digital predistortion (DPD) scheme is proposed for the linearization of power amplifiers (PAs) in broadcasting transmitters. The proposed DPD scheme is called the signal-based DPD to distinguish it from the conventional

Cooperative jamming (CJ) is considered as one of the crucial means in physical-layer security (PLS) for defending against eavesdropping. With the aid of the CJ signal from a friendly jammer, the eavesdropper’s channel quality will be intentionally
