1. 1. 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

   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

   University essay from Institutionen för informationsteknologi och medier

   Author : Bilal Hasan Qureshi; [2012]
   Keywords : Spectrum Sensing; Ray-tracing and Sector Antennas;

   Abstract : Spectrum sensing plays a key role for radio resource awareness in cognitive radio. To enhance the capabilities of cognitive radio nodes, exploiting the spatial resource in addition to frequency and time re-sources seems reasonable. READ MORE

6. 5. Spectrum Sensing in Cognitive Radio Systems using Energy Detection :  

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : YUHANG SUN; [2011]
   Keywords : Cognitive radio; spectrum sensing; energy detector;

   Abstract : Cognitive radio is a low-cost communication system, which can choose the available frequencies and waveforms automatically on the premise of avoiding interfering the licensed users. The spectrum sensing is the key enabling technology in cognitive radio networks. READ MORE
