Differential Reflecting Modulation for Reconfigurable Intelligent Surface-Based Communications

نویسندگان

چکیده

Reconfigurable intelligent surface (RIS) based communications have emerged as a new paradigm. This letter proposes differential reflecting modulation (DRM) scheme for RIS communication systems. In DRM, information bits are jointly carried by the activation permutations of patterns and phases transmitted signals, leading to that DRM can work without any channel state (CSI) at transmitter, or receiver. other words, release intricate resource-consuming estimation in transmission process. Simulation results show proposed pays an acceptable SNR penalty compared non-differential with coherent detection.

Reconfigurable intelligent optical backplane for parallel computing and communications.

A reconfigurable intelligent optical backplane architecture for parallel computing and communications is described. The backplane consists of a large number of reconfigurable optical channels organized in a ring with relatively simple point-to-point optical interconnections between neighboring smart-pixel arrays. The intelligent backplane can implement (l) dynamically reconfigurable connections...

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward

In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

Differential Amplitude Pulse-Position Modulation for Indoor Wireless Optical Communications

We propose a novel differential amplitude pulse-position modulation (DAPPM) for indoor optical wireless communications. DAPPM yields advantages over PPM, DPPM, and DH-PIMα in terms of bandwidth requirements, capacity, and peak-to-average power ratio (PAPR). The performance of a DAPPM system with an unequalized receiver is examined over nondispersive and dispersive channels. DAPPM can provide be...

Looking for Intelligent Reconfigurable Simulation

Simulation relates function to structure. Researching intelligence by simulating it to get to intelligent simulation demands the study of essential abstract structures: the human mind, the different types of hierarchies, and the simulation as relation between static and dynamic structures. Intelligence and Faith, as any other dichotomies, can converge together to integration, or can destroy eac...
