1. A Study of Lattice Reduction Detection Techniques for LTE Systems
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. LÄS MER
2. Optimization of Cognitive Radio in NLoS Backhauling of Small Cells
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : The increasing demand of data access and user experience result in deployment of new technologies (3G, LTE, WiMAX, Cognitive Radio), Long Term Evolution (LTE) is one of them which promises to fulfill the variable demand of subscribers through small cells instead of macro cells. The backhauling of the small cells in densely populated urban area is again a very difficult task to handle with Government regulations (eccentricities) and restrictions. LÄS MER
