A MATLAB software tool for the introduction of speech coding fundamentals in a DSP course
E. Painter,Andreas Spanias +1 more
TL;DR: A MATLAB educational simulation program was developed to explore and understand standardized speech coding algorithms such as the FS-1015 LPC-10e, theFS-1016 CELP, the ETSI GSM, the IS-54 VSELP and the G.728 LD-CELP algorithms.
Proceedings ArticleDOI
Transform coding algorithms for seismic data compression
TL;DR: An investigation is presented of transform-based seismic data compression of discrete orthogonal transforms such as the discrete Fourier transform (DFT), the discrete cosine transform (DCT), the Walsh-Hadamard transform (WHT), and the Karhunen-Loeve transform (KLT).
Proceedings ArticleDOI
Block time and frequency domain modified covariance algorithms
TL;DR: A block modified covariance algorithm (BMCA) is proposed for autoregressive (AR) parametric spectral estimation and its performance is evaluated in terms of computational complexity and convergence characteristics.
