In this paper, we consider secure transmission for the full duplex relay network. Aiming to improve the physical layer security, we propose a full duplex hybrid relaying-and-jamming (FDHRJ) scheme. In the FDHRJ scheme, we design a pre-coding matrix to form a jamming signal and let the relay simultaneously transmit both the desired signal and the jamming signal every slot. The destination can decode...
This letter investigates the outage performance in a full-duplex relay (FDR) channel that adopts an amplify-and-forward (AF) protocol. We provide a new closed-form expression for the outage probability that captures the joint effect of residual self-interference (RSI) and a direct link. In addition, when the processing delay of the relay is larger than 1, which is often the case in practice, the proposed...
In the paper, a fast analysis method by using near-field probes is proposed to diagnose radiated EMI mechanism for digital wireless speaker based on the inner relationship between radiated electromagnetic (EM) field and wave impedance. The results show CM noise dominates radiated EMI noise when frequency is below 300 MHz. Furthermore, a new method by using radio frequency (RF) circuit probes is used...
