  2. 17. Modeling Basic Physical Links in Acumen

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Muzeyen Hassen Esmael; [2012]
    Keywords : Acumen; Modulation and Demodulation; Simulation; RC Lowpass filter;

    Abstract : Simulation is the process of computing a behavior determined by a given model of a system of interest.  Modeling is the process of creating a model that formally describes a given class of system.  Modeling and simulation can be used to quickly and cheaply study and understand new technologies.

  3. 18. Embedding data in an audio signal, using acoustic OFDM

    University essay from Kommunikationssystem

    Author : Shuai Wang; [2011]
    Keywords : acoustic; acoustic OFDM; power control; embed;

    Abstract : The OFDM technology has been extensively used in many radio communicationtechnologies. For example, OFDM is the core technology applied in WiFi, WiMAXand LTE. Its main advantages include high bandwidth utilization, strong noise im-munity and the capability to resist frequency selective fading. READ MORE

  4. 19. Design of Multiplexed LO Single Mixer Receiver Front-End

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

    Author : Babak Taghavi; [2011]
    Keywords : ;

    Abstract : A new quadrature receiver architecture is studied and designed in this thesis. In conventional quadrature receivers each of I and Q channels are downconverted separately using a mixer and a local oscillator (LO) in each path. On the other hand, the proposed architecture is based on multiplexed LO signals. READ MORE

  5. 20. Performance Evaluation of LTE Physical Layer Using SC-FDMA & OFDMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abdul Samad Shaikh; Khatri Chandan Kumar; [2011]
    Keywords : OFDMA; SC-FDMA; LTE; BER; PAPR;

    Abstract : Since past few decades different types of cellular networks were launched and went successful on the radio links such as WiMAX, that became very popular because of its high data rate (70Mbps) and support for providing wireless internet services over 50km distance. The UMTS Long Term Evolution (LTE) is an emerging technology in the evolution of 3G cellular services. READ MORE
