On the Capacity and Performance of Generalized Spatial Modulation [PDF]
arXiv, 2016 Generalized spatial modulation (GSM) uses $N$ antenna elements but fewer radio frequency (RF) chains ($R$) at the transmitter. Spatial modulation and spatial multiplexing are special cases of GSM with $R=1$ and $R=N$, respectively. In GSM, apart from conveying information bits through $R$ modulation symbols, information bits are also conveyed through ...

, 2008 For several years the aircraft industry has been looking for a technology to provide at a reasonable cost a phone service onboard aircraft. Nevertheless, some technical hitches make successful calls via the terrestrial Global System for Mobile Communications (GSM) network impossible.

Gaussian Schell Source as Model for Slit-Collimated Atomic and Molecular Beams [PDF]
arXiv, 2008 We derive the spatial coherence and intensity profiles of beams emerging from two consecutive collimating apertures, and compare our results with data. We show how to make a Gaussian Schell-model (GSM) beam by assuming Gaussian apertures. Then we compare the intensity profile, the transverse coherence width and the divergence angle of a GSM beam with ...

Can Somebody Please Say What Gibbsian Statistical Mechanics Says? [PDF]
arXiv, 2018 Gibbsian statistical mechanics (GSM) is the most widely used version of statistical mechanics among working physicists. Yet a closer look at GSM reveals that it is unclear what the theory actually says and how it bears on experimental practice. The root cause of the difficulties is the status of the Averaging Principle, the proposition that what we ...
