  1. 21. Performance Evaluation of Error Correcting Techniques for OFDM Systems

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : Yasir Javed Qazi; Jawad Ahmed Malik; Safwan Muhammad; [2014]
    Keywords : OFDM; Linear block codes; Convolution codes; Reed-Solomon codes;

    Abstract : Orthogonal frequency-division multiplexing (OFDM) systems provide efficient spectral usage by allowing overlapping in the frequency domain. Additionally, they are highly immune to multipath delay spread. READ MORE

  4. 23. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Hadiyah Butt; Manjularani Padala; [2013]
    Keywords : ADPLL; PLL; DCO; TDC;

    Abstract : A phase-locked loop commonly known as PLL is widely used in communication systems. A PLL is used in radio, telecommunications, modulation and demodulation. It can be used for clock generation, clock recovery from data signals, clock distribution and as a frequency synthesizer. Most electronic circuits encounter the problem of the clock skew. READ MORE

  5. 24. Extraction of radio frequency quality metric from digital video broadcast streams by cable using software defined radio

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Viktor Eriksson; [2013]
    Keywords : QAM; DVB-C; MER; BER; Gardner; Phase locked loop; Mueller Muller; RRC-filter; Carrier recovery; Timing Recovery; Matched filtering;

    Abstract : The purpose of this master thesis was to investigate how effiecient the extractionof radiofrequency quality metrics from digital video broadcast (DVB) streamscan become using software defined radio. Software defined radio (SDR) is a fairlynew technology that offers you the possibility of very flexible receivers and transmitters where it is possible to upgrade the modulation and demodulation overtime.

  6. 25. Improvement for LDPC Coded OFDM Communication System over Power Line

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

    Author : Wu Dan; [2013]
    Keywords : low‐voltage power line communication LV‐PLC ; LDPC; OFDM; impulse noise suppression; Class‐A noise;

    Abstract : Power line communication has been around in past decades and gained renewed attention thanks to the demand of high-speed Internet access. With the significant advantages of existing infrastructure and accessibility to even remote areas, power grid has become one of the promising competitors for multi-media transmission in household.
