In this letter, we introduce two hybrid transmission schemes combining a passive reconfigurable intelligent surface (RIS) with decode-and-forward relaying in synergistic manner. The proposed offer flexible as well cost-and power-efficient solution for coverage extension future generation wireless networks. We present closed-form expressions the end-to-end signal-to-noise ratio of both and seque...

In this paper, we adopt the relay selection (RS) protocol proposed by Bletsas, Khisti, Reed and Lippman (2006) with Enhanced Dynamic Decode-and-Forward (EDDF) and network coding (NC) system in a two-hop two-way multi-relay network. All nodes are single-input single-output (SISO) and half-duplex, i.e., they cannot transmit and receive data simultaneously. The outage probability is analyzed and w...

In this paper, the particle filtering problem is investigated for a class of stochastic systems with multiple sensors under signal relays. To improve performance transmissions, relay deployed between each sensor and remote filter. Both amplify-and-forward (AF) decode-and-forward (DF) relays are considered certain transmission protocols. Stochastic series employed to describe multiplicative chan...
