Webspatial multiplexing rank improvement by increasing the available degrees of freedom in the channel [4]. Similarly, in higher frequencies, the channel can be dominated by one or two strong paths and an RIS can be used to increase the spectral efficiency as well. 1 To appear in National Science Review. Digital Object Identifier: WebMultiplexing efficiency has recently been proposed as a performance metric for characterizing the absolute efficiency of MIMO antennas in a reference channel. In this work, we generalize this metric to account for arbitrary propagation channels, so the impact of the channel can also be studied.

Antenna Design for Diversity and MIMO Application
WebFor discrete-aperture antennas,the EDoF depends on the size of MIMO, the antenna spacing, the signal fre-quency, and the distance. The aperture size of each antenna element does not affect the value of EDoF. Note that lim x→0 sin2(xNt) sin2 x = Nt 2, we obtain ε dis = 1 when d → ∞. This means only one data stream can be transmitted WebThis work presents a new technique for enhancing the performance of a multiple-input multiple-output (MIMO) antenna by improving its correlation coefficient ρ. A broadband dielectric structure is designed using the transformation electromagnetics (TE) concept to decorrelate the fields of closely placed radiating elements of an MIMO antenna, thereby … Web20 apr. 2024 · The peak gains and DG of the presented antenna were 4.6 dBi and 9.5 dB, respectively, ECC was less than 0.02, isolation was less than −22 dB, and multiplexing efficiency was greater than −3 dB. Additionally, a dielectric resonator MIMO antenna with a frustum shape was proposed for SWB application by the authors of [ 40 ]. pwc akademija
