  1. 1. Automatic Detection of Low Passability Terrain Features in the Scandinavian Mountains

    University essay from KTH/Geodesi och satellitpositionering

    Author : Fredrik Ahnlén; [2019]
    Keywords : Classification; Fuzzy Logic; Fuzzy Inference System; Automatic Mapping; Terrain Features; Land Cover Mapping; Cartography; Shrub; Mire; Stony Ground; Klassificering; Fuzzy Logic; Fuzzy Inference System; Automatisk Kartering; Terrängföremål; Marktäcke; Kartografi; Videsnår; Sankmark; Stenig Mark;

    Abstract : During recent years, much focus have been put on replacing time consuming manual mappingand classification tasks with automatic methods, having minimal human interaction. Now it ispossible to quickly classify land cover and terrain features covering large areas to a digital formatand with a high accuracy. READ MORE

  2. 2. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling; Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling; Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Mahesh Aleti; Rahamatulla Syed; Rajendra Prasad Chennupati; [2014]
    Keywords : Cognitive Radio; Power Control; the Fuzzy Interference System FIS ; ANFIS; “MIMO” “Multiple Input Multiple Output” ; “OFDM” “Orthogonal Frequency Division Multiplexing” ; AWGN; BER; SNR; Eb N0;

    Abstract : 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. READ MORE

  3. 3. Enhancements of an auto-thrustfunction using fuzzy logic

    University essay from KTH/Optimeringslära och systemteori

    Author : Gustav Öman Lundin; [2014]
    Keywords : Fuzzy logic; aircraft speed control; turbulence;

    Abstract : This master's thesis aims to investigate how fuzzy logic can be used to adapt the tuning of a speed control law during certain conditions such as turbulence. The objective is to lower the speed overshoot caused by the auto-thrust function as well as the general engine agitation. READ MORE

  4. 4. ANFIS BASED OPPURTUNISTIC POWER CONTROL FOR COGNITIVE RADIO IN SPECTRUM SHARING

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Joyraj Chakraborty; Venkata Krishna chaithanya varma. Jampana; [2013]
    Keywords : ANFIS; Fuzzy inference system; spectrum sharing;

    Abstract : Cognitive radio is a intelligent technology that helps in resolving the issue of spectrum scarcity. In a spectrum sharing network, where secondary user can communicate simultaneously along with the primary user in the same frequency band, one of the challenges in cognitive radio is to obtain balance between two conflicting goals that are to minimize the interference to the primary users and to improve the performance of the secondary user.

  5. 5. OPTIMIZED FUZZY BASED POWER CONTROL STRATEGY IN COGNITIVE RADIO NETWORKS IN MULTI FADING PROPAGATION ENVIRONMENTS

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Praneeth Kumar Bejjenki; Muneeb Ahmed Goraya; Syed Fovad Moid; [2013]
    Keywords : Cognitive Radio Networks; Spectrum Sharing Networks; Power Control; Takagi-Sugeno Fuzzy Inference System; m-Nakagami fading channel; OFDM.;

    Abstract : In this thesis we have considered a cognitive radio network (CRN) with a pair of primary user (PU) and secondary user (SU) in spectrum sharing networks in path-loss and without path-loss propagation environments under identically distributed m-Nakagami fading channel. The thesis consists of three parts. READ MORE
