This paper aims to optimize multiple #reconfigurable #intelligent #surfaces (#RISs) to control the signal propagation environment for maximizing the signal-to-interference-plus-noise ratio (SINR) in a #multiuser #MIMO system. The authors examine two approaches for managing interference and determining the optimal phase shifts for the RIS elements. They also evaluate the asymptotic expressions for the optimal phase shifts and maximum SINRs as the number of base station antennas becomes very large. ---- Somayeh Aghashahi More details can be found at this link: https://lnkd.in/edgnRK4Z

This paper studies #terahertz (#THz) #simultaneous #wireless #information #and #power #transfer (#SWIPT) systems. Since coherent information detection is challenging at THz frequencies and Schottky diodes may not be efficient for THz #energy #harvesting (#EH), we propose a novel THz SWIPT system design that employs unipolar #amplitude #shift #keying (#ASK) modulation at the #transmitter (#TX) and a #resonant-#tunnelling #diode (#RTD)-based EH circuit at the #receiver (#RX) to extract both information and power from the received signal. Furthermore, the authors propose a novel model for the dependence of the instantaneous output power of the RTD-based RX on the instantaneous received power, which is based on a non-linear and non-monotonic piecewise function, whose parameters are adjusted to fit circuit simulation results. ----Nikita Shanin, Simone Clochiatti, @Kenneth M.

10 high-speed #PCBlayout design rules 1. Have a common ground plane right below the signal traces 2. Ensure adequate spacing between vias to avoid hotspots 3. Place vias symmetrically to eliminate impedance discontinuities 4. Maintain minimum bends while routing 5. Add serpentines to length match the traces 6. Maintain at least 3W spacing between the signal traces to minimize crosstalk 7. Implement daisy chain routing to avoid long stubs 8. Do not place components and vias between differential pairs 9. Design differential pairs with symmetrical paths and keep signals in parallel 10.

Jabil and Keysight will host a workshop at EuMW in Paris next month on Phased Array Antennas for NTN. Early bird registration rate stops on Aug. 23. www.eumweek.com. Phased array antennas (PAA) are crucial for the convergence of NTN with terrestrial networks. As NTN advances, the industry is developing advanced PAAs to enable seamless connectivity between terrestrial and NTN components. These PAAs are complex in function and circuitry and physically large and heavy. They introduce new challenges to designers and manufactures in characterization, calibration, and production test. A PAA can have thousands of elements integrated with beamforming ICs and RF frontend components. How can we quickly and accurately characterize and calibrate these large antennas in OTA chambers to support large scale deployment? PAA’s beam steering performance is critical to managing the handover between NTN, TN, and intra/inter satellites. How should one design a network/front-haul setup to support these tests in R&D labs and production lines? Knowing the challenges of current PAA design in characterization and production, can we introduce new architectures and circuitries to improve their manufacturability? NTN PAAs are installed on satellites. Production test of PAAs for NTN should be more comprehensive than base station radio test as replacing a faulty PAA on satellites is far more costly. At the same time, for cost control, manufacturers need to reduce test time in production. What is the right balance? Can AI help to speed up test and fault diagnosis? In this workshop, we will have presentations from academia and industry to address these challenges from test methodology, measurement platform, test algorithms, product design, test equipment design, and production efficiency and reliability perspectives.
