  1. 1. Antenna Selection and Bit Allocation Strategies for Generalized Spatial Modulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nilab Ismailoglu; [2019]
    Keywords : ;

    Abstract : Spatial Modulation (SM) is a novel transmission technique for Multiple InputMultiple Output (MIMO) systems. In SM, a block of information bits is dividedinto two, and mapped to constellation symbols and spatial symbols. Spatialinformation is carried by the active transmit antenna index for each transmittedblock. READ MORE

  3. 2. Radio Localization with GSM

    University essay from Linköpings universitet/Reglerteknik

    Author : Simon Pålstam; [2016]
    Keywords : Radio Localization; GSM; Fake Base Station; FBS; TOA; RSS;

    Abstract : This thesis presents a feasibility study on unobtrusive localization of GSM en- abled cellphones using a Fake Base Station (FBS). An FBS is a radio transceiver that emulates the behaviour of a legitimate GSM Base Station (BS) to fool unal- tered cellphones to connect with it. READ MORE

  4. 3. Analysis and Design of Microwave Reconfigurable Filters in ESIW Technology

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Juan Rafael Sánchez Marín; María Trinidad Juliá Morte; [2015]
    Keywords : Reconfigurable; Microwave; Filters; ESIW; Empty; Substrate; Integrated; Waveguide;

    Abstract : Microwave filters are essential components in high frequency communication systems. The features required for these devices are increasing due to the increase in frequency, caused by the saturation of the electromagnetic spectrum. READ MORE

  5. 4. Ad Hoc Network Nodes Scheduling using DS and FH CDMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Farhan Khan; Muhammad Umer Khan and Noman Ellahi; [2013]
    Keywords : Ad Hoc Network; Node Scheduling; FH-CDMA; DS-CDMA;

    Abstract : Nowadays most communication networks like GSM, WLan or WiMAX are based on pre-existing infrastructure. These infrastructures are complicated, costly and difficult to deploy in very short time. Whereas Wireless Ad Hoc Networks are infrastructure-free self organizing networks which consist of co-operating nodes. READ MORE

  6. 5. Discrete Cosine Transform for Pre-coded EGPRS

    University essay from KTH/Signalbehandling

    Author : Chengzhou Jin; [2012]
    Keywords : ;

    Abstract : Due to the rapid growth of wireless multimedia service, new features such as improved spectral efficiency, latency and increased peak throughput are standardized in the current GSM/EDGE system. Higher order modulations and symbol rates are defined in Enhanced General Packet Radio Service phase 2 (EGPRS2) to achieve better throughput. READ MORE
