Initial Characterization of Massive Multi-User MIMO Channels at 2.6 GHz in Indoor and Outdoor Environments

The channel properties have a large influence on user separability in massive multi-user multiple-input multiple-output (massive MIMO) systems. In this paper we present spatio-temporal characteristics obtained from massive MIMO channel measurements at 2.6 GHz. The results are based on data acquired in both indoor and outdoor scenarios where a base station equipped with 64 dual-polarized antenna el

Procurement Procedures as predictors for cost and time overrun in construction

The choice of procedure during public procurement is assumed to affect the overall result of the project. When studying the construction industry; delivery methods, payment systems and project specific variables may affect the end result. The question here is if project success is predicted by choice of procurement procedures. A survey was done on 222 road and railroad construction projects in Swe

Close-ups from afar: the nature of the informal venture capital market in a spatial context

The availability of external equity finance is one of the vital conditions for emergence and growth of young entrepreneurial firms. Yet, the access to finance is both limited and unevenly distributed in geographical space. At the same time, there is anecdotal evidence that the informal venture capital market plays a significant role in providing small-scale geographically dispersed finance to entr
