Each antenna has a peak gain of 4.4?dBi with an average radiation efficiency of 92.5%. The proposed MIMO antenna is designed on a Rogers RO4003 substrate having a dielectric constant of 3.55, and a loss tangent of 0.0027 with a dimension of 700×700×55? μ m3. Further analyses of path...
SNR for different channel gain. Fig. 16 represents the 3D analysis of path loss which provides information and relation among path loss, the number of reflectors, and distance for RIS-assisted BackCom. The path loss is proportional to distance and inversely proportional to the number of ...
Channel gain maps are useful for various sensing and resource allocation tasks essential for the operation of cognitive radio networks. In this work, the channel gains are modeled as the tomographic accumulations of an underlying spatial loss field (SLF), which captures the attenuation in the ...
It should be also noted that the gain of the sum-rate capacity of the MIMO BC over the MIMO single user link for large number of users scales as follows: (11.39)limK→∞RBC(H(K),P)RSU(H(K),P)=MN, which shows that the gains over single-user transmission diminish N grows, ...

a SEM image of a topological polarization singular laser, where a semiconductor membrane serves as photonic crystal and gain material simultaneously. The lattice constant (\(a\)) is ~1240 nm, and the operation wavelength (\(\lambda\)) is ~1567 nm in free space. The length of the reci...
In addition, these techniques improve system performance at significantly lower cost than other techniques aiming to improve channel SNR, such as increased transmitter power or antenna gain [9]. Of the two error correction techniques, FEC is usually preferred in real-time video applications because ...
