  1. 1. Design of a 200Gbps externally modulated laser for opto-electronic integration

    University essay from KTH/Tillämpad fysik

    Author : Tianyu Jiang; [2022]
    Keywords : Optical modulator; Externally modulated laser; Traveling-wave; Electroabsorption; PSPICE; Optisk modulator; externmodulerad laser; Resande-våg; Elektroabsorption; PSPICE;

    Abstract : Segmented traveling wave electro-absorption modulators (TWEAMs) can provide a modulation speed above 100 Gb/s, which is needed in new optical communication networks. In the EU-project TWILIGHT, KTH continues the design work of TWEAMs in the EU-projects IPHOBAC and HECTO with the aim to design a new optical modulator to be integrated with an electronic layer.

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

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

    Author : Liping Wang; [2016]
    Keywords : LTE; MIMO; Lattice Reduction; MMSE; ZF; ML; Kronecker Model; Rayleigh Fading Channel; Technology and Engineering;

    Abstract : 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. READ MORE

  4. 3. Load Balancing in Microwave Networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Adeel Mohammad Malik; Muhammad Sheharyar Saeed; [2013]
    Keywords : ;

    Abstract : Microwave links are very commonly used in carrier networks especially towards the access side. They not only ease deployment of a network but are also very cost effective. However, they bring along a multitude of challenges which are characteristic of the wireless technology. Microwave links are fickle. READ MORE

  5. 4. Construction of FPGA-based Test Bench for QAM Modulators

    University essay from Elektroniska komponenter

    Author : Josef Hederström; [2010]
    Keywords : FPGA; Signal generation; Quadrature modulation; Software defined radio; Testbench; Radio communication; High datarate;

    Abstract : In todays fast evolving mobile communications the requirements of higher datarates are continuously increasing, pushing operators to upgrade the backhaul to support these speeds. A cost eective way of doing this is by using microwave links between base stations, but as the requirements of data rates increase, the capacity of the microwave links must be increased. READ MORE

  6. 5. Radio Resource Management in WiMAX

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Noman Shabbir; Hasnain Kasif; [2009]
    Keywords : RRM; WiMAX; Cell Planning; Link Budget;

    Abstract : Today, different types of cellular networks are actively working on the radio links. For instance, the Global System for Mobile Communication (GSM) is being used in nearly two hundred countries and currently it has around two and half billion users all over the world. READ MORE
