  1. 6. Local Impacts of Climate Change on Fortum´s Hydropower Production

    Master-uppsats, KTH/Vattendragsteknik

    Författare :Joakim Thanke Wiberg; [2016]
    Nyckelord :Global warming; climate variability; hydropower plants; spectral analysis;

    Sammanfattning : Background: Climate change and the consequences of global warming is probably one of the greatest issues of our time. Among other concerns, global warming is thought to have a great impact on hydrology worldwide. When the atmosphere warms up, river runoff patterns are altered. LÄS MER

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

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

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

    Sammanfattning : 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. 8. Performance Evaluation of LTE Physical Layer Using SC-FDMA & OFDMA

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Abdul Samad Shaikh; Khatri Chandan Kumar; [2011]
    Nyckelord :OFDMA; SC-FDMA; LTE; BER; PAPR;

    Sammanfattning : Since past few decades different types of cellular networks were launched and went successful on the radio links such as WiMAX, that became very popular because of its high data rate (70Mbps) and support for providing wireless internet services over 50km distance. The UMTS Long Term Evolution (LTE) is an emerging technology in the evolution of 3G cellular services. LÄS MER
