  1. 1. Hardware design and implementation of the Schmidl-Cox synchronization algorithm for an OFDM transceiver

    University essay from Uppsala universitet/Högenergifysik

    Author : Peter Morris; [2015]
    Keywords : ;

    Abstract : The subject of this document is the VHDL firmware implementation of a coarse synchronization method for a 4G/5G transceiver. The method of choice is the Schmidl-Cox synchronization algorithm that is applied to the OFDM transmission standard as preparation for later conversion to the FBMC method. READ MORE

  3. 2. 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

  4. 3. A Reconfigurable FFT Architecture for Variable Length and Multi-Streaming WiMax Wireless OFDM Standards

    University essay from Elektroniksystem

    Author : Boopal Padma Prasad; [2011]
    Keywords : FFT; FPGA; Reconfigurability; Wireless; OFDM; WiMax;

    Abstract : This paper presents a reconfigurable FFT architecture for variable length andmultistreaming WiMax wireless standard. The architecture processes 1 streamof 2048-pt FFT, up to 2 streams of 1024-pt FFT or up to 4 streams of 512-ptFFT. The architecture consists of 11 SDF pipelined stages and radix-2 butterflyis calculated in each stage. READ MORE

  5. 4. An FPGA implementation of a modulator for digital terrestrial television according to the DTMB standard

    University essay from Institutionen för systemteknik

    Author : Sebastian Abrahamsson; Markus Råbe; [2010]
    Keywords : DTMB; DTTB; DMB-T; FPGA; VHDL; OFDM; signal processing; ECC; IDFT; LDPC; BCH; convolutional; frequency interleaving; raised cosine; filter;

    Abstract : The increasing data rates in digital television networks increase the demands on data capacity of the current transmission channels. Through new standards, the capacity of exisiting channels is increased with new methods of error correction coding and modulation. READ MORE

  6. 5. Spectrum Optimization in Cognitive Radio Networks using Genetic Algorithms

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Adnan Azam; Taimoor Siddique; [2010]
    Keywords : EM; FCC; CR; QoS; GA; SDR; EC; GP; DSP; FPGA; BER; RF; FM; BPSK; QPSK; GMSK; 16 QAM; DPSK; MSK; OFDM; OOK; GW; FP; ABS; AWS;

    Abstract : The rapid revolution in wireless communication in past years has increased the demand of radio spectrum to fulfill quality of service (QoS) requirements of wireless applications, leading to spectrum overcrowding. To solve the spectrum overcrowding problem, cognitive radio (CR) has emerged as a leading technology because it can intelligently sense an unused spectrum without creating any harm to authorized users.
