  1. 16. 3D vegetation structure influence on boreal forest bird species richness

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Emil Larsson; [2017]
    Keywords : birds; species richness; vegetation structure; Lidar; laser data; bird point census count; Bird National Monitoring Program;

    Abstract : Bird populations across the world are in danger with decreasing numbers and more species continually becoming red-listed. One main driver behind this trend is human-caused habitat loss and degeneration, which in particular has been identified as a major threat in forested regions. READ MORE

  2. 17. Maximizing LTE performance with MIMO Systems

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Vunnam Praveen; [2016]
    Keywords : ;

    Abstract : The project explains Long Term Evolution (LTE) systems when used with Multiple-Input, MultipleOutput (MIMO) fulfill the growing demands in throughput and system robustness for the user. This is investigated by understanding the throughput capacity of LTE down-links in both spatial multiplexing and transmission diversity mode. READ MORE

  3. 18. Long Range Channel Predictions for Broadband Systems : Predictor antenna experiments and interpolation of Kalman predictions

    University essay from Uppsala universitet/Signaler och System

    Author : Joachim Björsell; [2016]
    Keywords : Channel prediction; Prediction interpolation; Predictor antenna; Predictor antenna measurements; Telecom; Telecommunication;

    Abstract : The field of wireless communication is under massive development and the demands on the cellular system, especially, are constantly increasing as the utilizing devices are increasing in number and diversity. A key component of wireless communication is the knowledge of the channel, i.e, how the signal is affected when sent over the wireless medium. READ MORE

  4. 19. A Study of Lattice Reduction Detection Techniques for LTE Systems

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik
