  1. 1. SIGNALBEHANDLING MED AVANCERAD BLUETOOTH-TEKNIK OCH OPTIMERADE OPERATIVSYSTEM : Optimera audiosystemet i ett avancerat inbyggt system med en fler-trådad programvara och synkroniserings mekanism

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Omar Ibrahim; [2023]
    Nyckelord :BM83 bluetooth; audio subsystem; Inter-IC sound; Digital Signal Processor; Operative System; DSP platform tests.;

    Sammanfattning : This study is about replacing an old bluetooth module with a new variant, namely the BM83 which is an integrated circuit that contains an internal DSP circuit, profiles and important functions such as noise reduction, acoustic echo removal and EQ filtering. The purpose of this study is to replace the old module with the BM83, as well as explore the internal DSP circuit in the BM83. LÄS MER

  3. 2. Application of formal verification and validation on modern multi-functional signalling system

    Master-uppsats, KTH/Transportplanering

    Författare :Shamsul Arefin; [2022]
    Nyckelord :;

    Sammanfattning : Demand for rail transport is increasing day by day. Rail is popular in public transport due to punctuality, regularity, and safety. However, we hear daily that rail traffic still has many problems to solve about incidents, near misses, and signal errors. LÄS MER

  4. 3. Inter-Satellite Link Design for Nanosatellites in New Space

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Andreas Fredmer; [2020]
    Nyckelord :Inter-satellite link; ISL; Space Communication; Nanosatellite; Saab AB; Fredmer; New Space;

    Sammanfattning : New Space is a phrase used to describe the expanding commercialization into the areas of space, for instance the Low Earth Orbit at approximately 500 km altitude. This is due to the decrease in cost as the satellites are becoming smaller and the transport vehicles cheaper. LÄS MER

  5. 4. Simulation of Attitude and Orbit Control for APEX CubeSat

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Niels de Graaf; [2020]
    Nyckelord :Orbital Control Simulation; Asteroid; Open Source; CAN bus; Microcontrollers; Software Verification Facility; Hardware in the loop HIL;

    Sammanfattning : CubeSats are becoming a game changer in the space industry. Appearing first for univer-sity mission, its popularity is increasing for commercial use and for deep space missionssuch as the on HERA mission that will orbit in 2026 around an asteroid as part of aplanetary defence mission.

  7. 5. En generisk delsystemsimulator - Tillämpad på antenndelsystemet i MIST-satelliten

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Louise Fischer; Mustafa Al-Janabi; [2019]
    Nyckelord :;

    Sammanfattning : Funktionell testning är en viktig process när man bygger en satellit. Det är emellertid inte lämpligt att ofta använda färdig flyghårdvara för testning. Arbetet i detta projekt har varit att konstruera en flygrepresentaterande modell av antennutrustningen för den KTH-studentbyggda MIST-satelliten. LÄS MER
