  1. 21. UWB-based wireless sensor network with medical application

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Joakim Lindström; [2018]
    Nyckelord :;

    Sammanfattning : This master thesis aims to develop a prototype of a wireless sensor network (WSN) using ultra wideband (UWB) radio and communication. The WSN consists of five sensor nodes and one sink which is connected to an Android smartphone. The smartphone acts as a sensor data management unit and has the ability to display sensor measurements. LÄS MER

  3. 22. Pilot Power Control and Assignment Games in MU-MIMO Systems

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

    Författare :Zhongyan Bi; [2018]
    Nyckelord :;

    Sammanfattning : In this work, we consider a MU-MIMO communication system forboth single cell and multi-cell cases. Other than the fundamental Rayleighchannel model which has been analysed intensively in previous works,we also adopt the Rician channel to model different types of wirelesslinks. LÄS MER

  4. 23. Efficient DPD Coefficient Extraction For Compensating Antenna Crosstalk And Mismatch Effects In Advanced Antenna System

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

    Författare :Himanshu Gaur; Md Zahidul Islam Shahin; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The demand for high data rates in a wireless communication system has experienced a remarkable growth over the last years. This demand is continually increasing with the growing number of wirelessly connected devices. Thus, there is a continuing hunt for increasing the data transmission rate in wireless communication systems. LÄS MER

  5. 24. Scheduler Algorithms for MU-MIMO

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

    Författare :Wissam Moustafa; Richard Mugisha; [2017]
    Nyckelord :Scheduling; Beamforming; TDD; TM-8; SRS; Downlink; Round Robin; SU-MIMO; MU-MIMO.; Technology and Engineering;

    Sammanfattning : In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. LÄS MER

  7. 25. Block Diagonalization Based Beamforming

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Darshan Patil; [2017]
    Nyckelord :;

    Sammanfattning : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.
