11. A comparison of 5G candidate waveforms subject to phase noise impairment at mm-wave frequencies
Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)Sammanfattning : Frequencies above 6 GHz are being considered by mobile communication industry for the deployment of future 5G networks. Large channel bandwidths above 6 GHz are likely to be used to serve diverse use cases and meet extreme user requirements. LÄS MER
12. Machine Learning for PAPR Distortion Reduction in OFDM Systems
Master-uppsats, KTH/SignalbehandlingSammanfattning : The purpose of the project is to investigate the possibility of using modern machine learning to model nonlinear analog devices like the Power Amplifier (PA), and study the feasibility of using such models in wireless systems design. Orthogonal frequency division multiplexing (OFDM) is one of the most prominent modulation technique used in several standards like 802. LÄS MER
13. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. LÄS MER
14. Performance Evaluation of Error Correcting Techniques for OFDM Systems
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för kommunikationssystemSammanfattning : Orthogonal frequency-division multiplexing (OFDM) systems provide efficient spectral usage by allowing overlapping in the frequency domain. Additionally, they are highly immune to multipath delay spread. LÄS MER
15. Qos Performance Analysis : Design And Development Of Voice And Video Mobility Over Long Term Evaluation (Lte) Model
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : The evolution of 3G systems has contributed to a significant amount of progress towards 4th generation wireless technology, Long Term Evolution (LTE). On the other hand, demand for more bandwidth has been evidenced by the ever growing usage of real-time application such as video conference. LÄS MER
