  1. 11. Estimating the Term Structure of Default Probabilities for Heterogeneous Credit Porfolios

    University essay from KTH/Matematisk statistik

    Author : Felix Bogren; [2015]
    Keywords : ;

    Abstract : The aim of this thesis is to estimate the term structure of default probabilities for heterogeneous credit portfolios. The term structure is defined as the cumulative distribution function (CDF) of the time until default. Since the CDF is the complement of the survival function, survival analysis is applied to estimate the term structures. READ MORE

  3. 12. Performance Evaluation and Comparison of Coherent and Incoherent Receivers under Atmospheric Turbulence

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Mohamed Kazaludeen Akbar; [2014]
    Keywords : Free-Space Optical Communication FSO ; Signal to Noise Ratio SNR ; Avalanche Photodiode APD ; Probability Density Function PDF ; Cumulative Distribution Function CDF ; Bit Error Rate BER ;

    Abstract : Optical free space communication system faces the major challenge because of the atmospheric condition. Signals receive in the ground station using two different types of receivers (Coherent detection and Intensity Modulation and Direct Detection (IM/DD)). READ MORE

  4. 13. Full Duplex Multiuser MIMO with Massive Arrays

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Hussain Wannas; [2014]
    Keywords : Full-Duplex; Massive MIMO; MIMO; MU-MIMO;

    Abstract : Half-Duplex Multiuser Multiple-Input Multiple-Output (HD MU-MIMO) systemscurrently employed in communication systems are not experiencing the selfinterference(SI) problem but they are not optimal in terms of efficiency and interms of resources used (time and frequency resources). Ignoring the effect of largescalefading, we start by explaining the uplink (UL) and downlink (DL) parts ofthe MU-MIMO system and how the sum-rate is calculated. READ MORE

  5. 14. Performance Analysis of Cognitive Radio Network over SIMO System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Iqbal Hasan Haider; MD. Fazla Rabby; [2012]
    Keywords : Cognitive Radio; Outage Probability; Symbol Error Probability; Single Input Multiple Output; Selection Combining; Spectrum Sharing System.;

    Abstract : As resources are limited, radio spectrum becomes congested due to the growth of wireless applications. However, measurements address the fact that most of the licensed spectrums experience low utilization even in intensively teeming areas. READ MORE
