1. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. READ MORE

2. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Power allocation algorithms that determine how much power should be allocated to pilot and data symbols play an important role in addressing the trade-off between accurate channel estimation and high high spectral efficiency for data symbols in the presence of time-varying fading channels. Dealing with this trade-off is highly non-trivial when the channel changes or ages rapidly in time. READ MORE

3. Processing of full waveform sonic data for shear wave velocity at the Ketzin CO2 storage site
University essay from GeofysikAbstract : The accumulation of carbon dioxide gas (CO2) in the atmosphere is considered be the main cause of global warming effects. These emissions can be reduced substantially by capturing and storing the CO2. The CO2SINK project started in April 2004 in the northeast German Basin (NEGB) at the town of Ketzin near Berlin, Germany. READ MORE
