TL;DR: A number of key technical challenges as well as the potential solutions associated with 6G, including physical-layer transmission techniques, network designs, security approaches, and testbed developments are outlined.

TL;DR: A general survey of the SM design framework as well as of its intrinsic limits is provided, focusing on the associated transceiver design, on spatial constellation optimization, on link adaptation techniques, on distributed/cooperative protocol design issues, and on their meritorious variants.

TL;DR: Both theoretical analysis and simulation results are presented to show that the proposed OFDM with interleaved sucarrier-index modulation (OFDM-ISIM) can achieve better system performance than conventional OFDM-IM and OfDM with low-order modulation schemes such as binary phase shift keying, quadrature phase shiftkeying and 16 quadratures amplitude modulation.

TL;DR: In this article, a morphotropic phase boundary driven by epitaxial strain was observed in lead-free multiferroic BiFeO3 thin films and the strain-driven phase transitions have been widely reported as iso-symmetric Cc-Cc by recent works.
