  1. 1. High-Performance Beamforming for Radar Technology : A Comparative Study of GPU Beamforming Algorithms

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Oscar Lindgren; [2022]
    Nyckelord :Accelerated signal processing software; Beamforming; Electronic warfare; Electromagnetic waves; Emitter identification; Radar technology; Accelererad signalbehandlingsmjukvara; Beamforming; Elektronisk krigsföring; Elektromagnetiska vågor; Sändaridentifikation; Radarteknologi;

    Sammanfattning : Radar technology is widely used in today´s society, whether it is the localisation and identification of aircraft in air traffic control systems, ships in harbour management systems, or the weather forecast presented on the news. In military applications, such as in fighter jets or missile lock-on systems, the speed at which the radar processes incoming data is essential to ensure a successful outcome. LÄS MER

  3. 2. Active- integrated aperture lens antenna

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesus Ventas Muñoz de Lucas; [2021]
    Nyckelord :;

    Sammanfattning : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. LÄS MER

  4. 3. Low Complexity Beamformer structures for application in Hearing Aids

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Eleni Koutrouli; [2018]
    Nyckelord :hearing aids; beamformers; MVDR algorithm; microphone arrays;

    Sammanfattning : Background noise is particularly damaging to speech intelligibility for people with hearing loss. The problem of reducing noise in hearing aids is one of great importance and great difficulty. Over the years, many solutions and different algorithms have been implemented in order to provide the optimal solution to the problem. LÄS MER

  5. 4. Speech Enhancement in Hands-Free Device (Hearing Aid) with emphasis on Elko's Beamformer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :TELAGAREDDI S N U V RAMESH; [2012]
    Nyckelord :Speech Enhancement; Speech intelligibility; Speech Communication and Beamforming ;

    Sammanfattning : In general, an uncontrolled environment may contain degradation components like background noise, speech from other speakers etc. along with required speech components. It is very tough to concentrate only on speech signals in presence of background noise for normal listeners and hearing impaired persons. LÄS MER

  7. 5. Multi Channel Sub Band Wiener Beamformer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Rajesh Amerineni; [2012]
    Nyckelord :Reverberation; Linear Microphone array; WOLA Filter Bank; Wiener Beamformer; SRP-PHAT;

    Sammanfattning : With the recent advance in microphone array speech processing, achieving robustness of speaker localization becomes most significant aspect. At the same time considerable research growth is performed in developing the multiple microphone sensors equipped rooms are developed also called as smart rooms for real time applications. LÄS MER
