چکیده
Intelligent reflecting surface (IRS) has recently emerged as a new solution to enhance wireless communication performance via passive signal reflection. In this letter, we unlock the potential of IRS controller in relaying information and propose novel IRS-assisted system with both reflection active relaying. Specifically, jointly optimize time allocations for decode-and-forward (DF) by beamforming maximize achievable rate proposed system. We also compare conventional without relaying, reveal conditions one outperform other. Simulation results demonstrate that design can significantly improve coverage/rate systems.

IRS-MT: Tool for Intelligent Resource Allocation
A tool for optimizing cost and time of a workflow execution with respect to allocation of multi-purpose resources is presented. The optimization is done as a result of simulations, which take into account the cost and time associated with each of the resources, when allocated to transitions in Petri nets representing a workflow. These attributes can be collected and updated based on the logs of...

متن کاملResource Allocation for Mixed RF and Hybrid RF/FSO Relaying
In this paper, we consider a mixed RF and hybrid RF/FSO system where several mobile users transmit their data over an RF link to a relay node (e.g. a small cell base station) and the relay forwards the information to a destination (e.g. a macro cell base station) over a hybrid RF/FSO backhaul link. The relay and the destination employ multiple antennas for transmission and reception over the RF...
