1. 16. Performance evaluation of higher order modulations in OFDM systems

   University essay from Institutionen för fysik och elektroteknik (IFE)

   Author : Veerapu Sravankumar; Malineni Jayaram Navaneeth; Chandran Vivek; [2013]
   Keywords : ;

   Abstract : In this thesis we design and simulate OFDM (Orthogonal Frequency Division Multiplexing) to study the performance of the OFDM system at higher order modulation schemes. It is very important to evaluate performance of the communication system, to test the efficiency and quality of the service it can provide. READ MORE

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

   University essay from 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

4. 18. Theoretical Investigation of a new OFDM Access-Network Topology (OTONES)

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Aditya Kakkar; [2013]
   Keywords : OTONES; SSB Method; Image Rejection; Novel Bedrosian Method; Orthogonal Frequency Division Multiplexing OFDM ; Optical Network Unit ONU ; Optical Line Terminal OLT ; Coherent Receiver; Remote Heterodyne Detection; Optical Access Network; WDM network;

   Abstract : Recent studies on growth of telecomm sector depict an ever rising demand for high bandwidth applications such as on-line gaming, high definition television and many more. This demand is coupled with increase in internet connected utilities per house hold - each requiring a portion of bandwidth. READ MORE

5. 19. Implementation of 64-point FFTs as a building block for OFDM-based standards with respect to different criteria

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Sarojanarayanamurthy Rajavari Krishnaih Lokanadhan; [2013]
   Keywords : ;

   Abstract : Abstract This master thesis implements a critical block: Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT) for standards using Orthogonal Frequency Division Multiplexing (OFDM). They are used in OFDM systems for modulating / demodulating subcarriers. READ MORE

6. 20. PERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKSPERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKS

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : CLEMENT RANJITH ANTHIKKAD & IRFAN AHMED BAIG; [2013]
   Keywords : Orthogonal Frequency Division Multiplexing OFDM ; Peak-to-Average Power Ratio PAPR ; Complementary Cumulative Distribution Function CCDF ; Partial Transmit Sequence PTS ; Tone Reservation TR .;

   Abstract : This paper presents a new hybrid PAPR reduction technique for the OFDM signal, which combines a multiple symbol representations method with a signal clipping method. The clipping method is a nonlinear PAPR reduction scheme, where the amplitude of the signal is limited to a given threshold. READ MORE
