  1. 1. Blind Acoustic Feedback Cancellation for an AUV

    University essay from Linköpings universitet/Reglerteknik

    Author : Hampus Frick; [2023]
    Keywords : acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Abstract : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. READ MORE

  3. 2. Implementation of Spectrum Analysis Functionality for IQ-Signal.

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

    Author : Gedion Biredaw Anbessa; [2020]
    Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

    Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

  4. 3. Eye opening monitor for optimized self-adaptation of low-power equalizers in multi-gigabit serial links

    University essay from Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

    Author : Anand Narayanan; [2013]
    Keywords : Inter-symbol interference; Adaptive Equalizer; Eye opening monitor; Receiver; Continuous time linear equalizer;

    Abstract : In modern day communication systems, there is a constant demand for increase in transmission rates. This is however limited by the bandwidth limitation of the channel. Inter symbol interference (ISI) imposes a great threat to increasing data rates by degrading the signal quality. READ MORE

  5. 4. Adaptive filters applied on radar signals

    University essay from Signaler och System

    Author : Daniel Salminen; [2013]
    Keywords : LMS; RLS; adaptive filters; radar;

    Abstract : This master thesis has been performed at SAAB AB in Järfälla, Sweden.A radar warning receiver must alert the user when someone highlights it with radarsignals. Radar signals used today varies and has a wide frequency band. In order todetect all possible radar signals the radar warning receiver must have a widebandwidth. READ MORE

  6. 5. Microphone Array Wiener Beamforming with modeling of SRP- PHAT for Speaker Localization

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : SRISESHUKUMAR BASAVA; [2012]
    Keywords : MIcrophone array; Wiener beamforming; Source localization;

    Abstract : The use of microphone arrays to acquire and recognize speech in meetings (conference) poses several problems for speech processing as there exist many speakers within a small space, typically around a table. The necessity to design a suitable microphone array system with minimum noise and more efficient localization algorithms is drawing attention of researchers to work on it. READ MORE
