Eavesdropping on GSM: state-of-affairs [PDF]

arXiv, 2011
In the almost 20 years since GSM was deployed several security problems have been found, both in the protocols and in the - originally secret - cryptography. However, practical exploits of these weaknesses are complicated because of all the signal processing involved and have not been seen much outside of their use by law enforcement agencies.

Asymptotic scaling properties of the posterior mean and variance in the Gaussian scale mixture model [PDF]

arXiv, 2017
The Gaussian scale mixture model (GSM) is a simple yet powerful probabilistic generative model of natural image patches. In line with the well-established idea that sensory processing is adapted to the statistics of the natural environment, the GSM has also been considered a model of the early visual system, as a reasonable "first-order" approximation ...

Toward Scalable Many-Body Calculations for Nuclear Open Quantum Systems using the Gamow Shell Model [PDF]

, 2019
Drip-line nuclei have very different properties from those of the valley of stability, as they are weakly bound and resonant. Therefore, the models devised for stable nuclei can no longer be applied therein. Hence, a new theoretical tool, the Gamow Shell Model (GSM), has been developed to study the many-body states occurring at the limits of the ...

Generalized Spatial Modulation in Indoor Wireless Visible Light Communication [PDF]

arXiv, 2015
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses $N_t$ light emitting diodes (LED), but activates only $N_a$ of them at a given time.

Facilitating Machine to Machine (M2M) Communication using GSM Network [PDF]

Published in the Proceedings of 2012 International Conference on the Internet of Things (IoT), Wuxi; presented in M2M-CTS'12 Workshop, 2013
In this paper a method to facilitate M2M communication using existing GSM networks is proposed - as M2M devices primarily use SMS as their data bearer, the focus is on increasing the number of devices that can use the associated GSM signaling channels at a time.

Transmit Antenna Selection for Massive MIMO-GSM with Machine Learning [PDF]

arXiv, 2019
A dynamic and flexible generalized spatial modulation (GSM) framework is proposed for massive MIMO systems. Our framework is leveraged on the utilization of machine learning methods for GSM in order to improve the error performance in presence of correlated channels and channel estimation errors.
