Among the circular configurations of receiver positions, the optimal location is selected for three-receiver structure based on the extensive simulations. This paper employs the linear regression with supervised learning for angle-of-arrival prediction. A previous study has verified the performance of time-of-flight estimation by utilizing the non-parametric and parametric homomorphic deconvolution algorithms. The proposed system consists of two computational stages as homomorphic deconvolution and machine learning stage.
The individual receivers are connected by the single analog microphone network which provides the superimposed signal over simple connectivity based on asynchronized analog circuit. This paper proposes a single-channel sound localization system for transport with multiple receivers. The conventional sound source localization systems require the significant complexity because of multiple synchronized analog-to-digital conversion channels as well as the scalable algorithms. This book introduces the corresponding MATLAB functions and programs in every chapter with examples, and the final chapter introduces the actual real-time filter from MATLAB, and the digital signal processor (DSP).Īimed primarily at undergraduate students in electrical and electronic engineering, this book enables the reader to implement a digital filter using MATLAB and the DSP.
The author introduces the mathematics in a conceptual manner with figures to illustrate the physical meaning of the equations involved.Ĭhapter six builds on these concepts and discusses advanced filter design, and chapter seven discusses matters of practical implementation. The following chapters provide answers to these questions, introducing signals in the discrete domain, Fourier analysis, filters in the time domain and the Z-transform. In contrast to the conventional teaching approach, the book offers a top-down approach which first introduces students to digital filter design, provoking questions about the mathematical tools required. This textbook provides an introduction to the study of digital signal processing, employing a top-to-bottom structure to motivate the reader, a graphical approach to the solution of the signal processing mathematics, and extensive use of MATLAB.
