Design of RLS Wiener Smoother and Filter for Colored Observation Noise in Linear Discrete-Time Stochastic Systems: 《Journal of Signal and Information Processing》2012年第3期316-329,共14页Seiichi Nakamori; Almost estimators are designed for the white observation noise. In the estimation problems, rather than the white observation noise, there might be actual cases where the observation noise is modeled by the colored no...; 关键词：Discrete-Time Stochastic System RLS WIENER Filte RLS WIENER FIXED-POINT Smoother COLORED OBSERVATION Noise COVARIANCE Information

Non-Stationary Signal Segmentation and Separation from Joint Time-Frequency Plane: 《Journal of Signal and Information Processing》2012年第3期339-343,共5页Abdullah Ali Alshehri; Multi-components sinusoidal engineering signals who are non-stationary signals were considered in this study since their separation and segmentations are of great interests in many engineering fields. In most cases, t...; 关键词：Signal Segmentation TIME-FREQUENCY Distribution Short-Time FOURIER TRANSFORM NON-STATIONARY WIENER MASKING

RLS Wiener Predictor with Uncertain Observations in Linear Discrete-Time Stochastic Systems: 《Journal of Signal and Information Processing》2011年第3期152-158,共7页Seiichi Nakamori Raquel Caballero-águila Aurora Hermoso-Carazo Josefa Linares-Pérez; This paper proposes recursive least-squares (RLS) l-step ahead predictor and filtering algorithms with uncertain observations in linear discrete-time stochastic systems. The observation equation is given by y(k)=y(k)z...; 关键词：Estimation Theory Synthesis of Stochastic Systems RLS WIENER PREDICTOR UNCERTAIN Observations MARKOV PROBABILITY

Speech Enhancement Using Cross-Correlation Compensated Multi-Band Wiener Filter Combined with Harmonic Regeneration被引量：1: 《Journal of Signal and Information Processing》2011年第2期117-124,共8页Venkata Rama Rao Rama Murthy K. Srinivasa Rao; The speech signal in general is corrupted by noise and the noise signal does not affect the speech signal uniformly over the entire spectrum. An improved Wiener filtering method is proposed in this paper for reducing ...; 关键词：SPEECH Enhancement WIENER Filter Critical Band and SPEECH HARMONICS
