2. Development of new criteria for train detection and evaluation in critical conditions
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Railway signaling is of paramount importance to ensure traffic management andsafety on the rail network. The main lines are divided into sections called ‘blocks’,which are governed by a fixed signal installation. To prevent trains from colliding,each block allows one train at once. READ MORE

4. Frequency Tracking Using Digital Cavities
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Digital cavities are efficient algorithms for comb filters with very low computational costs. They have been used to precisely measure the amplitude and phase of high frequency signals (few giga samples per second) from data acquired by high speed digitizers 80 GSps. READ MORE

5. Modulation schemes in ambient backscatter communication
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : This thesis presents a study of different modulation schemes in the context of backscatter communication. Backscatter communication is a way of wireless communication where no active signal is transmitted. Instead surrounding signals are modified to transmit data. READ MORE
