1. 6. Visualizing Carrier Aggregation Combinations

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Fredrik Helders; [2019]
   Keywords : LTE; Carrier Aggregation; Visualization; Graph traversal; Load balancing; 4G; 3GPP;

   Abstract : As wireless communications is becoming an increasingly important part of ourevery day lives, the amount of transmitted data is constantly growing, creating ademand for ever-increasing data rates. One of the technologies used for boostingdata rates is carrier aggregation, which allows for wireless units to combine multipleconnections to the cellular network. READ MORE

3. 7. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tomás Soares da Costa; [2019]
   Keywords : ;

   Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE

4. 8. Predicting inter-frequency measurements in an LTE network using supervised machine learning : a comparative study of learning algorithms and data processing techniques

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Adrian Sonnert; [2018]
   Keywords : Telecommunications; Telecom; Mobile networks; 4G; LTE; LTE-A; Machine learning; Random forest; Gradient boosting; Neural network; Multi-layer perceptron; Logistic regression; Frequency measurements; Handover; Load balancing; Carrier aggregation;

   Abstract : With increasing demands on network reliability and speed, network suppliers need to effectivize their communications algorithms. Frequency measurements are a core part of mobile network communications, increasing their effectiveness would increase the effectiveness of many network processes such as handovers, load balancing, and carrier aggregation.

6. 10. Passive Inter-modulation Cancellation in FDD System

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Fan Chen; [2017]
   Keywords : Technology and Engineering;

   Abstract : Passive inter-modulation (PIM) shows up when two or more RF signals are mixed together via the nonlinear passive devices. With the rapid development and expansion of the wireless com-munication networks, PIM is recognized as one of the most critical issues. READ MORE
