Explaining Spatial Diversity in Entrepreneurship
Abstract This study reviews the relationship between cultural diversity and entrepreneurship, focusing on whether local knowledge stocks and knowledge diversity amplify its effects. Using a unique dataset including immigrant entrepreneurship data across sectors, we confirm a positive effect of entrepreneurs’ cultural diversity on ...Alessandra Colombelli +2 more

Distributed rotation recovers spatial diversity
2010 IEEE International Symposium on Information Theory, 2010In relay networks, a conventional way to exploit spatial diversity is to introduce distributed space-time processing at the relays. In our work, we show that even simple time-varying distributed rotation can recover spatial diversity. The main idea is to convert the inherent spatial diversity to time diversity by creating an artificial fast fading ...

Smart antenna and spatial diversity-combining
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003The smart antenna and spatial diversity-combining receiver are two of the most important spatial signal processing technologies. This paper studies the radio propagation characteristics of the transmission path, spatio-temporal channel model and channel characteristics in different environments.

Gain of spatial diversity with conjoint signals
2017 IEEE AFRICON, 2017This paper proposes a novel method of achieving conjoint coding gain without additional signal measurement requirements. In the proposed scheme, received signals in a spatial diversity system are used to synthesize additional conjoint signals within the neighbourhood of receive antennas. These excess signals are assumed to be from virtual antennas.

Spatial Diversity in the Global City
This book, at the nexus of migration and urban studies, sheds new light on a long-neglected group of transmigrants and the global city of Tokyo. Using extensive empirical material on transnational migrants from above and below, it locates and better specifies spatial diversification in Tokyo and beyond.openaire +2 more sources
