Complexity in international society: theorising fragmentation and linkages in primary and secondary institutions [PDF]
, 2021 This article seeks to contribute to theorising the institutional structure of international society by exploring synergies between complex systems thinking and the English School theory of International Relations (IR).

Complex Quadrature Spatial Modulation
ETRI Journal, 2017 In this paper, we propose a spatial modulation (SM) scheme referred to as complex quadrature spatial modulation (CQSM). In contrast to quadrature spatial modulation (QSM), CQSM transmits two complex signal constellation symbols on the real and quadrature spatial dimensions at each channel use, increasing the spectral efficiency.

Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]
, 2013 In this paper, we consider spatial modulation (SM) operating in a frequency-selective single-carrier (SC) communication scenario and propose zero-padding instead of the cyclic-prefix considered in the existing literature.

Reduced-Complexity Noncoherently Detected Differential Space-Time Shift Keying
, 2011 Motivated by the recent development of spatial modulation (SM) and differential space-time shift keying (DSTSK), we propose a reduced-complexity conventional differential detector (CDD) as well as its reduced-complexity multiple-symbol differential ...

Environment InternationalThe use of cars in cities has many negative impacts, including pollution, noise and the use of space. Yet, detecting factors that reduce the use of cars is a serious challenge, particularly across different regions.

Low-complexity transmit antenna selection for spatial modulation
, 2015 A low-complexity transmit antenna selection (TAS) scheme is proposed for spatial modulation systems to provide a better trade-off between computational complexity and system performance.

EVOLUTION OF SPATIAL COMPLEXITY IN ROMANIA: NETWORKING, DIFFERENTIATION [PDF]
Revue Roumaine de Géographie, 2013 The spatial complexity is negatively correlated with regional specialization. Demonstration of how regional specialization has been evolving has relevance in studying the dynamics of spatial complexity.

Serious Games in Spatial Planning: Strengths, Limitations and Support Frameworks
International Journal of Serious Games, 2022 Serious games are being developed in many fields of research and proving to be valuable practical tools. In the planning field, games can help approach complexity and engage more participants through first-person experimentation.
