Synchronization of a TDMA-OFDM frequency hopping system

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

Increasing the Photon Energy for Photonuclear Experiments in MAX-lab by Phase Modulating the SLED Pulse

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
