1. Digital Front End Algorithms for Sub-Band Full Duplex
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

2. Out-of-band transfer with Android to configure pre-shared secrets into sensor nodes
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. LÄS MER
3. Offset-PLL based frequency up-conversion for low spurious transmission
Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknikSammanfattning : The goal of this final year project is to investigate various techniques to up-convert a baseband signal into radio frequency signals, and to investigate the practical problems encountered in an offset phase locked loop design by implementation. Phase locked loops are commonly used in radio transmitters and receivers to generate accurate RF signals from a low-frequency reference. LÄS MER
