  3. 2. Simulation-Based Stochastic Blockage Model for Millimeter-wave Communication

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mihret Getye Sidelel; [2020]
    Nyckelord :;

    Sammanfattning : Recently, the growing demand for high data rates in wireless communication, together with the scarcity of spectrum in existing microwave bands, has motivated the use of millimeter-wave (mmWave) bands for 5G and future wireless communications. Even though mmWaves are potential candidates for fulfilling this rising demand, they come along with their own drawbacks that need to be addressed. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Nyckelord :LTE; MIMO; Lattice Reduction; MMSE; ZF; ML; Kronecker Model; Rayleigh Fading Channel; Technology and Engineering;

    Sammanfattning : MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. LÄS MER

  5. 4. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Rui Ma; Ioannis Chountalas; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. LÄS MER

  7. 5. An IEEE 802.15.4 Packet Error Classification Algorithm : Discriminating Between Multipath Fading and Attenuation and WLAN

    Master-uppsats, Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Författare :Nan Chen; [2014]
    Nyckelord :WSN; error discrimination; MFA; WLAN interference; F-BER; RSSI; LQI; CC2420;

    Sammanfattning : In wireless sensor networks, communications are usually destroyed by signal attenuation, multipath fading and different kinds of interferences like WLAN and microwave oven interference. In order to build a stable wireless communication system, reactions like retransmission mechanisms are necessary. LÄS MER
