  1. 11. Digital Techniques for Compensation of Radio Frequency Impairments in Mobile Communication Terminals

    University essay from Elektroniska komponenter

    Author : Sudarshan Gandla; [2011]
    Keywords : ;

    Abstract : The 3G and 4G systems make use of spectrum efficient modulation techniques which has variable amplitude. The variable amplitude methods usually use carrier‘s amplitude and phase to carry the message signal. READ MORE

  3. 12. Digital Methods for Reduction of IQ Imbalance in OFDM Systems

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Daxious Mengistu Wendemu; [2010]
    Keywords : IQ imbalance; least square LS ; least mean algorithm LMS ; OFDM;

    Abstract : Orthogonal frequency division multiplexing (OFDM) based systems are susceptible to radio front end induced impairments. These impairments caused by as a consequence of imbalances in the In-phase (I) and Quadrature-phase (Q) branches. IQ imbalances are worries to be addressed for the Superhetrodyne and the zero IF architectures in analog domain. READ MORE

  4. 13. ON DVB-H RADIO FREQUENCY PLANNING: : ADJUSTMENT OF A PROPAGATION MODEL THROUGH MEASUREMENT CAMPAIGN RESULTS

    University essay from Institutionen för teknik och byggd miljö

    Author : Gema Roig; [2008]
    Keywords : Propagation; model; adjustment; planning; radioplanning;

    Abstract : The present Master Thesis analyzes the DVB-H radio Frequency Network Planning problematic, studying the influence of a propagation model used in the calculation of network coverage. In this way, the aim of this work is the design of a procedure and algorithm to adjust a propagation model considering measurement campaigns performed in different environments (dense-urban, urban, sub-urban and rural).

  5. 14. Interference Cancellation in a Full duplex System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Thomas Ahlström; Claes Bengtsson; [2008]
    Keywords : Technology and Engineering;

    Abstract : In a full duplex system as WCDMA a mobile phone transmits and receives at the same time, but at different frequencies. The transmitted signal will cause interference in the receiver which must be suppressed to not get degraded sensitivity in the receiver. READ MORE

  6. 15. Performance study of IEEE 802.16d (Fixed WiMAX) Physical layer with Adaptive Antenna System

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Ahmer Ali Bajwa; Junaid Anwar Awan; [2008]
    Keywords : WiMAX IEEE 802.16d ; OFDM; Smart Antennas; AAS; LMS; Pre-FFT beamformer; SUI channel; Rician Fading; BER.;

    Abstract : In this thesis work, WiMAX (IEEE 802.16d) PHY layer with underlying OFDM technology and an optional feature called Adaptive Antenna System has been considered. The SUI-3 channel model (Rician fading) is used for creating fading phenomena. READ MORE
