An efficient low-cost time-hopping impulse radio for high data rate transmission

We present an efficient, low-cost implementation of time-hopping impulse radio that fulfills the spectral mask mandated by the FCC and is suitable for high-data-rate, short-range communications. The system was proposed to the IEEE 802.15.3a group for standardization as high-datarate personal-area network (PAN). Key features are: (i) all-baseband implementation obviates the need for local oscillato

Optimal Wigner Cross-Spectrum Estimation

An expression for the mean-square error (MSE) optimal Wigner cross-spectrum estimator is derived within a wide class of estimators. Using this expression and a simplemodel we are able to construct a new estimator which turns out to be superior compared to standard estimators such as Thomson multitapers and Welch method on simulated data.

Getting out of the black hole. Plant closures and local business renewal

Abstract in UndeterminedA more or less continuous process of structural change, not least due to a globalizing economy, poses a number of challenges to regions and local communities. However, when firms or whole industries are phasing out, windows of opportunity open up. Empirical analyses of a recent plant closure in the periphery of the Skane Region in Sweden point at the importance of retaining

Is anticorruption neoliberal plot? Assessming the anticorruption project in Southeast Europe

The consolidation of a global anticorruption regime can be seen has a combination of international policy instruments, ideologies about good and bad governance, and a whole set of promises, programmes and practices all intended to reduce corruption. After nearly two decades, we can give this assemblage a name: Anticorruptionism. This paper reviews the history of anticorruptionism and the current s

African farm trajectories and the sub-continental food crisis

Abstract in UndeterminedAfrican agriculture is more dynamic than one would expect, given the chronic food crisis in the sub-continent. Due to macro-economic and political preconditions, however, farmers’ dynamism is channelled into other directions than would be required to attain self-sufficiency in food grains. This is the main conclusion of this study of farm dynamics in eight African countries
