  1. 21. Implementation of CMMB System using Software Defined Radio (SDR) Platform

    University essay from Datorteknik

    Author : Haohao Gu; He Zhang; [2010]
    Keywords : CMMB; OFDM; SDR; wireless; digital broadcasting;

    Abstract : CMMB (China Multimedia Mobile Broadingcasting) is a wireless broadcastingchannel standard for low bandwidth, low cost hand-held digital TV is adopted byall continental Chinese government TV broadcasting companies and some HongKong private TV broadcasting companies. The business potential is high, yet thefuture is hard to predict because it might be replaced by GB200600 or DTMB. READ MORE

  3. 22. PERFORMANCE ANALYSIS OF MULTIPLE ANTENNA TECHNIQUES IN WiMAX

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Yousaf Ali Shah; [2010]
    Keywords : WiMAX; Capacity Analysis; STBC; MIMO; SFBC;

    Abstract : The modern wireless systems are required to have high voice quality and data rate. Since our concern is most with cattering environment, antenna diversity is a practically effective and widely applied technique to reduce the effect of multipath fading. READ MORE

  4. 23. Comparative study of WiMAX and LTE uplink using SDCMA and LSCMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Jaswini Reddy Potuganuma; [2010]
    Keywords : Wimax; LTE uplink; physical layer; SDCMA; LSCMA; FSE; blind equalizer;

    Abstract : Blind equalizers are widely used in wireless communications for minimizing Inter Symbol Interference (ISI). The Constant Modulus Algorithm (CMA) is one of the popular blind equalizers used in broad band applications. This master’s thesis investigates the Steepest Descent Constant Modulus Algorithm (SDCMA) i.e. READ MORE

  5. 24. Spectrum Optimization in Cognitive Radio Networks using Genetic Algorithms

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Adnan Azam; Taimoor Siddique; [2010]
    Keywords : EM; FCC; CR; QoS; GA; SDR; EC; GP; DSP; FPGA; BER; RF; FM; BPSK; QPSK; GMSK; 16 QAM; DPSK; MSK; OFDM; OOK; GW; FP; ABS; AWS;

    Abstract : The rapid revolution in wireless communication in past years has increased the demand of radio spectrum to fulfill quality of service (QoS) requirements of wireless applications, leading to spectrum overcrowding. To solve the spectrum overcrowding problem, cognitive radio (CR) has emerged as a leading technology because it can intelligently sense an unused spectrum without creating any harm to authorized users.
