Telephoto Zoom Monocular Telescope is the first attempt to use nano-etching technology, nano-array technology, mesoporous assembly technology, thin-film mosaic technology and nano-optical materials to make the flatness error of the lens reach 10nm. Link to buy 👉 https://lnkd.in/dhT_ybun The luminous flux reaches 30 times that of ordinary telescopes with the same diameter. The resolution angle is 47 times that of ordinary telescopes with the same diameter. The maximum magnification reached 300 times.This is the first monocular to achieve this magnification and clarity on such a small scale.

This paper proposes a scheme called #joint #delay-#Doppler #index #modulation #orthogonal #time #frequency #space (#JDDIM-#OTFS) to enhance reliability in OTFS systems to satisfy the rigorous requirements of forthcoming communication systems. This scheme activates delay or #Doppler #resource elements in a subframe, and in order to obtain higher spectral efficiency, the authors use different constellations for each active resource block. Furthermore, they utilize a #low-#complex #detector with the help of a #greedy #approach. Moreover, a theoretical upper bound is derived for the #bit #error #rate (#BER). ----Yusuf İslam Tek, Ertugrul Basar More details can be found at this link: https://lnkd.in/grByheMG
