1. 21. Implementation and Evaluation of Spectral Subtraction with Minimum Statistics using WOLA and FFT Modulated Filter Banks

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Peddi Srinivas Rao; Vallabhaneni Sreelatha; [2014]
   Keywords : Speech Enhancement; Filter Bank; Spectral Subtraction; Wiener Filtering; PESQ; DFT ; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

   Abstract : In communication system environment speech signal is corrupted due to presence of additive acoustic noise, so with this distortion the effective communication is degraded in terms of the quality and intelligibility of speech. Now present research is going how effectively acoustic noise can be eliminated without affecting the original speech quality, this tends to be our challenging in this current research thesis work.

3. 22. 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

4. 23. Power System Harmonics Analysis of HighPower Variable Speed Drives

   University essay from KTH/Elektrisk energiomvandling

   Author : Michael Scheidiger; [2014]
   Keywords : ;

   Abstract : Power system harmonics are a topic of significant concern when considering power quality issues in systems containing Variable Speed Drives. The extent to which grid-connected power electronics based motor drives affect power quality is tightly enforced through standards, and must be adhered to. READ MORE
