  1. 1. Discrete Cosine Transform for Pre-coded EGPRS

    Master-uppsats, KTH/Signalbehandling

    Författare :Chengzhou Jin; [2012]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : This thesis deals with output power calibration of a mobile platform that supports EGPRS.Two different topics are examined. First some different measurement methods are compared concerning cost efficiency, accuracy, and speed and later measurements are carried out on a mobile platform. LÄS MER

  7. 5. Link QualityControl (LQC) i GPRS/EGPRS

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Sorosh Seddigh; [2003]
    Nyckelord :Datorteknik; LQC; GSM; GPRS; EDGE; Incremental redundancy; Link Adaptation; Datorteknik;

    Sammanfattning : This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. LÄS MER
