  1. 6. 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

  3. 7. Adaptive Sub band GSC Beam forming using Linear Microphone-Array for Noise Reduction/Speech Enhancement.

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mamun Ahmed; [2012]
    Keywords : Generalized Side lobe Canceller GSC ; Blocking matrix; Microphone array; Sub band; SNR. ;

    Abstract : This project presents the description, design and the implementation of a 4-channel microphone array that is an adaptive sub-band generalized side lobe canceller (GSC) beam former uses for video conferencing, hands-free telephony etc, in a noisy environment for speech enhancement as well as noise suppression. The side lobe canceller evaluated with both Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) adaptation. READ MORE

    Keywords : Speech enhancement; Generalized sidelobe canceller; Wiener beamformer; Normalized least mean square algorithm.;

    Abstract : Now a day’s communication through laptops is drastically increasing in numerous fields. During the communication between person to person through laptops the speech signals is contaminated by the other speech interference signals. READ MORE

  5. 9. BLIND DECONVOLUTION AND ADAPTIVE ALGORITHMS FOR DE-REVERBERATION

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : SURYAVAMSI ATRESYA UPPALURU; [2012]
    Keywords : Adaptive algorithms; CMA; Reverberation; Reverberation index; Speech Distortion.;

    Abstract : De-reverberation of speech signals in a hands-free scenario by adaptive algorithms has been a research topic for several years now. However, it is still a challenging problem because of the nature of common room impulse response (RIR). READ MORE

  6. 10. Performance Analysis of Adaptive Algorithms based on different parameters Implemented for Acoustic Echo Cancellation in Speech Signals

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Swathi Kotte; [2011]
    Keywords : least mean square LMS Algorithm; Leaky Least mean square LLMS Algorithm; Normalized Least Mean Square NLMS Algorithm and Recursive Least Square RLS Algorithm ; additive white Gaussian noise ; Return Loss Enhancement ERLE ; signal to noise ratio;

    Abstract : Echo cancellation in voice communication is a process of removing the echo to improve the clarity, quality of the voice signals by suppressing the silence signal which prevents echoes during transmission through networks. There are two types of echo in voice communication: Hybrid echo cancellation and Acoustic echo cancellation. READ MORE
