  2. 1. On Cooperative Communications and Its Application to Mobile Multimedia

    Author : Quang Trung Duong; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the rapid growth of multimedia services, future generations of wireless communications require higher data rates and a more reliable transmission link while keeping satisfactory quality of service. In this respect, multipleinput multiple-output (MIMO) antenna systems have been considered as an efficient approach to address these demands by offering significant multiplexing and diversity gains over single-antenna systems without increasing requirements on radio resources such as bandwidth and power.

  4. 2. On the Performance Analysis of Cooperative Communications with Practical Constraints

    Author : Quang Trung Duong; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : With the rapid development of multimedia services, wireless communication engineers may face a major challenge to meet the demand of higher data-rate communication over error-prone mobile radio channels. As a promising solution, the concept of cooperative communication, where a so-called relay node is formed to assist the direct link, has recently been applied to alleviate the severe pathloss and shadowing effects in wireless systems.

  7. 5. Mortality in rural Vietnam : validity of routine reporting and experiences from a surveillance system

    Author : Tran Quang Huy; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Death surveillance; mortality validity; sensitive research; surveyor’s experiences; vital registration; Vietnam.;

    Abstract : Background: Findings from many low-income countries, Vietnam included, show that mortality estimates based on death data collected in routine systems have low validity. Aims: The overall aim of this thesis is to examine and discuss the validity of mortality estimates based on data collected in different systems in a rural setting in Northern Vietnam and to identify factors that can influence the reporting and registration of deaths, all in order to make recommendations for improvement of death registration.
