We present a simplified derivation of the extended Baum-Welch procedure, which shows that it can be used for Maximum Mutual Information (MMI) of a large class of continuous emission density hidden Markov models (HMMs). We use the extended Baum-Welch procedure for discriminative estimation of MLLR-type speaker adaptation transformations. The resulting adaptation procedure, termed Conditional Max...

Orotic acid is utilized by many mammalian and bacterial systems for the biosynthesis of the pyrimidines found in ribonucleic (UNA) and deoxyribonucleic (DNA) acids. 6-Uracil methyl sulfone (UMS) is one of several orotic acid analogs which have been synthesized and studied by Greenbaum, Hohnes, and Welch (1, 2, 15). Hohnes and Welch have shown (4) that UMS noncompetitively inhibits the growth of...

Spectral analysis is an important area in signal processing with wide range of application. A low complexity algorithm to compute the power spectral density (PSD) using the Welch method is presented in this paper. The Welch algorithm computes spectral power at the cost of high computational complexity. In order to reduce the complexity and hardware utilization pipelining FFT approach is used. I...

Codebooks with small inner-product correlation are applied in many practical applications including direct spread code division multiple access communications, space-time codes and compressed sensing. It is extremely difficult to construct codebooks achieving the Welch or Levenshtein bound. In this paper, we firstly generalize Jacobi sums over finite fields and secondly obtain asymptotically op...
