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...

Reconfigurable intelligent surfaces (RISs) represent a new technology that can shape the radio wave propagation in wireless networks and offers great variety of possible performance implementation gains. Motivated by this, we study achievable rate optimization for multi-stream multiple-input multiple-output (MIMO) systems equipped with an RIS, formulate joint problem covariance matrix transmitt...

Reconfigurable multiple-input multiple-output can provide performance gains over traditional MIMO by reshaping the channels, i.e., introducing more channel realizations. In this paper, we focus on achievable rate maximization pattern design for reconfigurable systems. Firstly, introduce matrix representation of (PR-MIMO), based which a problem is formulated. To further reveal effect radiation w...

In this work, lossy distributed compression of a pair correlated sources is considered. Conventionally, Shannon's random coding arguments - using randomly generated unstructured codebooks whose blocklength taken to be asymptotically large are used derive achievability results. However, in some multi-terminal communications scenarios, codes with constant finite certain architectures leads improv...
