  1. 1. DIFFERENTIAL CODE SHIFTED REFERENCE IMPULSE-BASED COOPERATIVE UWB COMMUNICATION SYSTEM

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : Shoaib Amjad; Rohail Khan Malhi; Muhammad Burhan; [2013]
    Keywords : Bit error rate; Cooperative system; Differential code shift Reference and Ultra wide band communication.;

    Abstract : Cooperative Impulse Response – Ultra Wideband (IR-UWB) communication is a radio technology very popular for short range communication systems as it enables single-antenna mobiles in a multi-user environment to share their antennas by creating virtual MIMO to achieve transmit diversity. In order to improve the cooperative IR-UWB system performance, we are going to use Differential Code Shifted Reference (DCSR). READ MORE

  3. 2. Impact of non-idealities and integrator leakage on the performance of IR-UWB receiver front end

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

    Author : Tharakaramu Navineni; [2012]
    Keywords : IR-UWB; non-coherent energy detector; system modeling; non-idealities; integrator leakage; BER; Matlab;

    Abstract : UWB has the huge potential to impact the present communication systems due to its enormous available bandwidth, range/data rate trade-off, and potential for very low cost operation. According to FCC, Ultra Wideband (UWB) radio signal defined as a signal that occupies a bandwidth of 500 MHz or fractional bandwidth larger than 20% with strict limits on its power spectral density to -41.

  4. 3. Cognitive Radio for Short Range Systems based on Ultra-Wideband

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : ABDULLAH AL-MAMUN; MOHAMMAD RAFIQ ULLAH; [2011]
    Keywords : Cognitive Radio; UWB; Spectrum Sensing; Multitaper Spectrum Estimation;

    Abstract : Cognitive Radio (CR) has been proposed as a promising and effective technology to improve radio spectrum utilization. It can change its transmitter parameters depending on the environment in which it operate based on interaction. In CR, a number of different methods of spectrum sensing are used to identify the presence of signal transmission. READ MORE
