  1. 1. Is attained height associated with overnutrition measures in adolescents? : A cross-sectional analysis of 15 years’ follow-up data in the Maternal and Infant Nutrition Interventions in Matlab (MINIMat) study in rural Bangladesh

    University essay from Uppsala universitet/Internationell mödra- och barnhälsovård (IMCH)

    Author : Thet Lynn; [2019]
    Keywords : nutrition; malnutrition; overnutrition; attained height; height; sitting height; BMI; adolescents; Bangladesh;

    Abstract : Background: As overnutrition rises along with nutrition transition in low- and middle-income settings such as Bangladesh, evaluating metabolic risk factors using overnutrition measures in adolescents is important. Before doing such evaluation, a preliminary step should be taken to attest the independence of overnutrition measures from total height. READ MORE

  3. 2. Digital Predistortion for Broadcast FM repeaters

    University essay from KTH/Signalbehandling

    Author : Manne Tallmarken; [2011]
    Keywords : ;

    Abstract : This thesis presents the design and implementation of a memoryless and adaptive digital predistorter used to linearize a power amplier. Specically, it deals with the implementation of a so-called constantgain predistorter, based on a lookup table, on a digital signal processing board built around an FPGA. READ MORE

  4. 3. 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.

  5. 4. Channel Estimation in GPRS based Communication System using Bayesian Demodulation.

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Dileep Kumar Appana; Chinni Anil Kumar; Nagappan Palaniappan Nagappan; [2009]
    Keywords : Bayesian; techniques; demodulation; demodulator; GPRS; rayleigh; fading; channel; dileep; appana; chinni; anil; nagappan; palaniappan; blekinge; tekniska; högskolan; institue; technology; master; thesis;

    Abstract : 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. READ MORE

  6. 5. DAB Transmission System Simulation

    University essay from Institutionen för systemteknik

    Author : Héctor Uhalte Bilbao; [2004]
    Keywords : Electronics; DAB; Terrestrial digital broadcasting; OFDM; COFDM; IFFT; FFT; SFN; SimulinkTM< sup>; Differential modulator.; Elektronik;

    Abstract : DAB (Digital Audio Broadcasting) is the radio digital system developed as an european standard by the ETSI, EN 300 400, based on the Eureka-147 group works, to improve the performance of the analogue radio systems (AM and FM). The system is based on the OFDM technology which allows DAB to exploit the spectrum frequencies in a better way with a higher quality of sound for mobile receivers specially. READ MORE
