In OFDM-based UWB baseband, synchronizer plays a key role to the performance of the whole system. Therefore achieving an area and power efficient architecture at least SNR loss becomes the main challenge of synchronizer design. To meet 528 Msamples/s throughput, the parallel architecture is used in current approaches. But it leads to higher area and power consumption. In this paper, we propose an
This dissertation presents an inquiry into existing evidence, underlying assumptions, and the rapid diffusion of conditional cash transfers (CCTs) in Latin America. Equally concerned with empirical research on CCTs’ assumed capabilities and the programmes’ political economy and social policy contexts, this inquiry combines systematic analyses and case studies from field work in Uruguay and Guatema
We present a time division multiple access-orthogonal frequency division multiplexing (TDMA-OFDM)-based radio interface proposal for the Universal Mobile Telecommunication System (UMTS). We focus on synchronization and present an implementable algorithm for the tracking of the mobiles' time and frequency offsets at the base station in the uplink. This algorithm is based on estimation methods that

The nuclear physics facility at MAX-lab requires high energy electrons for photonuclear experiments. These electrons are first accelerated in two LINACs that are fed via a SLED system. Arcing in the waveguide structures is currently the limiting factor of the available electron energy. In this report, the implementation of a phase modulation scheme into the injector system is presented. This makes
