  1. 1. Implementation and Analysis of Spectrum Sensing Algorithms for SIMO Links

    Master-uppsats, Kommunikationssystem; Tekniska högskolan

    Författare :Techin Eamrurksiri; [2013]
    Nyckelord :cognitive radio; USRP; OFDM; Spectrum sensing; GLRT; SDR;

    Sammanfattning : Cognitive radio is an autonomous transceiver that is continuously sensing theongoing communication in its environment, it then starts the communication whenever it is appropriate. Therefore, cognitive radio helps improving the spectrum utilization of the overall communication system. LÄS MER

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

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Sarojanarayanamurthy Rajavari Krishnaih Lokanadhan; [2013]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 3. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Samiallah Shahid; Saqib Mohammad; [2013]
    Nyckelord :LTE-Advanced; Downlink; Transceiver; Physical Layer;

    Sammanfattning : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. LÄS MER
