A new configuration for the adaptive beamforming technology has been presented in this research work. We modified structure of uniform linear array (ULA) such a way that correct beam can be formed uniformly all azimuth angles. For ULA composed M antennas, we place two extra elements on top and bottom (at axis). Then, develop mathematical model or same. To investigate efficacy proposed antenna c...

-This paper presents the Cancellation of an acoustic echo. Such echo canceller is essential to control the echoes generated by the acoustic coupling between the microphone and loudspeaker in hands free telephones or teleconferencing applications. Conventional acoustic echo canceller encounters problems like slow convergence rate (especially for speech signal) and high computational complexity a...

Prediction of EEG signal from past samples is needed for early diagnosis of patients, suffering from frequent epileptic seizure and/or psychotherapeutic treatment of psychiatric patients. This paper compares the performance of various digital filter algorithms to identify the right candidate for application in EEG prediction. The study includes variation of filter order and past sample size, an...
