Description: Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in dustry. Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. Acoustic echo cancellation is a common occurrence in today’s telecommunication systems. The signal interference caused by acoustic echo is distracting to users and causes a reduction in the quality of the communication. This paper focuses on the use of LMS and NLMS algorithms to reduce this unwanted echo, thus increasing communication quality. -Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry.

Description: For this
project, we simulated and implemented a real-time acoustic
beamformer using MATLAB for simulations and the
TDS3230 DSK for the real-time implementaion. Although
the final system does not meet all of our initial goals, it
does successfully demonstrate beamforming concepts.

Description: The computation of the time delay of arrival (TDOA) between each of the considered channels and the reference channel is repeated along the recording in order for the beamforming to respond to changes in the speaker. In this implementation it is computed every 250ms (called segment size or analysis scroll) over a window of 500ms (called the analysis window) which covers the current analysis segment and the next. The size of the analysis window and of the segment size constitute a tradeoff. A big analysis window or segment window lead to a reduction in the resolution of changes in the TDOA. On the other hand, using a very small analysis window reduces the robustness of the cross-correlation estimation, as less acoustic frames are used to compute it. The reduction of the segment size also increases the computational cost of the system, while not increasing the quality of the output signal. Platform: |
