  1. 41. Maximum Capacity Antenna Design for an Indoor MIMO UWB Communication System

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Ran Liu; Hao Liu; [2012]
    Nyckelord :MIMO; UWB; Antenna Design; In-door Communication and Capacity Analysis;

    Sammanfattning : Ultra-wideband (UWB) offers a high data rate transmission, however it only can be used in short distance communication due to its low power restricted by regulations, therefore it is applicable for an indoor scenario. Within an enclosed (indoor) scenario, there exist many possible multipaths of electromagnetic waves which lead to an effect known as fading [Big07]. LÄS MER
