Holographic Integrated Sensing and Communications: Principles, Technology, and Implementation

چکیده
Integrated sensing and communication (ISAC) has attracted much attention as a promising approach to alleviate spectrum congestion. However, traditional ISAC systems rely on phased arrays provide high spatial diversity, where enormous power-consuming components such phase shifters are used, leading the power consumption. In this article, we introduce holographic ISAC, new paradigm enable diversity with low consumption by using reconfigurable surfaces (RHSs), which is an innovative type of planar antenna densely deployed metamaterial elements. We first hardware structure working principle RHS then propose novel beamforming scheme for ISAC. Moreover, build RHS-enabled prototype evaluate its performance. Simulation experimental results verify feasibility reveal great potential reducing Furthermore, future research directions key challenges related discussed.

The Educational Technology Integration and Implementation Principles (eTIPs) are six statements that describe the K-12 classroom and school-level conditions under which the use of technology will be most effective. The eTIPs are an example of materials that can aid teachers in designing instruction and participating in creating supportive conditions for technology supported classroom instruction.
متن کاملThe strong and weak holographic principles
We review the different proposals which have so far been made for the holographic principle and the related entropy bounds and classify them into the strong, null and weak forms. These are analyzed, with the aim of discovering which may hold at the level of the full quantum theory of gravity. We find that only the weak forms, which constrain the information available to observers on boundaries,...
