  1. 6. Is the Cyclic Prefix Needed in Massive MIMO?

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Valens Nsengiyumva; [2016]
    Keywords : Cyclic Prefix in Massive MIMO;

    Abstract : Massive multiple-input-multiple-output (MIMO) is a wireless communication technologythat usesa large number of antennas at the base station and servesmultiple terminals over the same time-frequency resource.This technique can achievehigher data rates than existing communication technology, which only serves one terminal per resource.

  3. 7. Adaptive Beamforming for Next Generation Cellular System

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

    Author : Sebastian Andersson; William Tidelund; [2016]
    Keywords : Adaptive; Beamforming; Precoding; 5G; Zero Forcing; MRT; Maximum Ratio Transmission; LTE; Wireless Communication; Technology and Engineering;

    Abstract : In this work aMatlab model of a simplified LTE system has been implemented. The PUSCH and PDSCH signal chains has been used for reception and transmission of data and DM-RS symbols are used as pilots. Moreover, the model supports communication and interference between multiple users and base station antennas. READ MORE

  4. 8. MIMO Channel Equalization and Symbol Detection using Multilayer Neural Network

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Athar Waseem; A.H.M Sadath Hossain; [2013]
    Keywords : MIMO; ISI; NN; SER; Channel Equalizer; QAM;

    Abstract : In recent years Multiple Input Multiple Output (MIMO) systems have been employed in wireless communication systems to reach the goals of high data rate. A MIMO use multiple antennas at both transmitting and receiving ends. These antennas communicate with each other on the same frequency band and help in linearly increasing the channel capacity.

  5. 9. Channel estimation in mobile wireless systems

    University essay from KTH/Signalbehandling

    Author : Pazi Alli Idd; [2012]
    Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

    Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.

  6. 10. LTE Uplink Modeling and Channel Estimation

    University essay from Datorteknik

    Author : Mohsin Niaz Ahmed; [2011]
    Keywords : LTE; Uplink; Channel Estimation; OFDMA; SC-FDMA;

    Abstract : This master thesis investigates the uplink transmition from User Equipment (UE) to base station in LET (Long Term Evolution) and channel estimation using pilot symbols with parameter defined in 3GPP (3rd Generation Partnership Project) specifications. The purpose of the thesis was to implement a simulator which can generate uplink signal as it is generated by UE. READ MORE
