  1. 1. PERFORMANCE ANALYSIS ON MODULATION TECHNIQUES OF W-CDMA IN MULTIPATH FADING CHANNEL

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :AUN ALI TAHIR; FENG ZHAO; [2009]
    Nyckelord :Final Thesis as Part for Master program in Electrical Engineering with Emphasis on Telecommunication;

    Sammanfattning : The transmission from base station to mobile or downlink transmission using M-ary Quadrature Amplitude modulation (QAM) and Quadrature phase shift keying (QPSK) modulation scheme are consider in W-CDMA system. We can analysis the performance of these modulation techniques when the system is subjected to AWGN and multipath Rayleigh fading are consider in the channel. LÄS MER

    Sammanfattning : With the increase use of portable devices such as Personal Digital Assistants (PDA), laptops, voice and data integrated cell phones and many more, there is a need of wireless communication method using air as the medium to transmit and receive information between terminals. Radio waves propagate from transmitting antenna and travel through free space undergoing reflections, diffractions and scattering. LÄS MER

  4. 3. Development of a MATLAB Simulation Environment for Vehicle-to-Vehicle and Infrastructure Communication Based on IEEE 802.11p

    Master-uppsats, Institutionen för teknik och byggd miljö

    Författare :Samaneh Shooshtary; [2008]
    Nyckelord :IEEE 802.11p; Vehicle-to-Vehicle communications; MATLAB Simulink; WinProp; WLAN;

    Sammanfattning : This thesis describes the simulation of the proposed IEEE 802.11p Physical layer (PHY). A MATLAB simulation is carried out in order to analyze baseband processing of the transceiver. Orthogonal Frequency Division Multiplexing (OFDM) is applied in this project according to the IEEE 802.
