  1. 1. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

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

    Author : Rui Ma; Ioannis Chountalas; [2015]
    Keywords : Technology and Engineering;

    Abstract : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. READ MORE

  3. 2. Propagation Model for Fresh Food : Fundamental Principle and Measurement Analysis

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Bharath Ranganathan; [2012]
    Keywords : Narrowband Measurements; Propagation; Impulse response; pathloss;

    Abstract : The global fresh food tracking system (FFT) is widely used service based on monitoring a set of primary environmental conditions during the transportation of fresh food using the GSM, RFID and WSN. In order to provide design guidelines for such devices, it is therefore important to develop effective channel model and see how the fresh food affects the transmitted electromagnetic signals.

  5. 4. Performance Evaluation of Power Control Algorithms in Cellular Radio Communication Systems

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Bala Satish Appuni; Vamsi Krishna Vemasani; [2004]
    Keywords : Power Control; CIR; SIR; CDMA; GSM;

    Abstract : Radio resources in wireless communication systems, implementing different multiple access techniques, must be wisely managed. This perspective is pivotal since the variations in propagation channel are very fast and the system is highly complex due to random and unpredictable movement of mobile users continuously. READ MORE
