A conceptual study of OFDM-based multiple access schemes: Part 2 - Channel estimation in the uplink

This paper deals with the design of channel estimators in the uplink of an OFDM based multi-user system. First, we propose a user allocation scheme that is based on the aim to use the correlation of the radio channel for channel estimation purposes. Further, we present the linear MMSE channel estimator based on a few pilot tones. We present an error analysis that proves valuable in the evaluation

Improved Models for DC-DC Converters

To obtain high performance control of a dc-dc converter, a good model of the converter is needed. It is suitable to consider the load to be included in the converter model since it usually affects the dynamics. The load is often the most variable part of this system. If the load current and the output voltage are measured there are good possibilities to obtain a good model of the load on-line. Ada

A model for prediction of temperature in steel structure protected by intumescent coating, based on tests in the Cone Calorimeter

Intumescent coating is an important fire protection method for steel structures. Traditionally its fire properties have been evaluated by performing furnace tests using a standardized test procedure and following a standardized time-temperature curve. This procedure is restrictive in performance based fire safety engineering design since it limits the fire condition to the standard one only. In th
