According to (1), Friis’s Law states that as the range increases, the transmitted and reflected power density in the far-field diminishes proportionally to the inverse square of the distance as expressed in (2). However, when it comes to the near-field region, electric and magnetic fields...
The linear MMSE detector has certain advantages with respect to the near–far problem and can be used to develop a channel estimation algorithm. In this paper, an efficient iterative method for near–far resistant single-user mobile radio channel estimation in slow fading multi-path direct ...
This disadvantage turns out be a great advantage and a flagship selling point for NFC technology as far as security is concerned. Along with the numerous benefits of NFC technology, researchers and technologists also are aware of the security and privacy concerns that comes along with technology. ...
Depending on how far out of town you are, it may not be obvious what your best bet for high-speed internet service is. These days everyone wants fiber internet, but fiber is typically only available in heavily populated areas. Cable is seldom an option for rural internet in Campton Hills,...
2020). Many studies indicated that near transfer can be more easily observed in gaming contexts. The skills required are closely related and thus transfer is more direct and likely to be more effective (e.g., Liu & Jeong,2022). Far transfer, such as applying problem-solving skills from ...

The deployment of XL-MIMO, especially at high-frequency bands, leads to users being located in the near-field region instead of the conventional far-field. This letter proposes efficient model-based deep learning algorithms for estimating the near-field wireless channel of XL-MIMO communications. ...
Rob Aitken, who was an Arm fellow at the time of this interview, describes the problem with memories. “A memory cell as provided by a foundry will not operate in the near-threshold region. If you need it to operate at a low voltage, you need a custom memory. This is because of ...
mobile networksDistributed systemsGroup key managementPGKMThe following paper deals with the problem of computing a safety perimeter, i.e., where the electromagnetic field due to a radiating system exceeds a certain electromagnetic value. The flexibility of the source reconstruction method (SRM) is ...
Finally, for interference such as noise, Synopsys’ Molina, said one option is to make the power grid as robust as possible. “That may mean over-designing the width of the power grid in order to minimize dynamic IR drop issue. Some people would go so far as to try to minimize their ...
