Cascade Rls with Subsection Adaptation
نویسندگان
چکیده
Speech coding or speech compression is one of the important aspects of speech communications nowadays. By coding the speech, the speed needed to transmit the digitized speech, called the bit rate, can be reduced. This means that for a certain speech communications channel, the lower the bit rate of the speech coding, the more communicating parties can be carried on that channel. This research has as its main application the extraction of the parameters of human speech for speech coding purposes.

A fast Gauss-Newton parallel-cascade adaptive truncated Volterra filter
This paper introduces a computationally e cient Gauss-Newton type adaptation algorithm for parallel-cascade realizations of truncated Volterra systems with arbitrary, but nite order nonlinearity. Parallel-cascade realizations implement higher-order Volterra systems using parallel and multiplicative combinations of lower-order Volterra systems. The complexity of our system is comparable to the c...
متن کاملAdaptive Learning Algorithm for Principal Component Analysis With Partial Data
In this paper a fast and ecient adaptive learning algorithm for estimation of the principal components is developed. It seems to be especially useful in applications with changing environment , where the learning process has to be repeated in on{line manner. The approach can be called the cascade recursive least square (CRLS) method, as it combines a cascade (hierarchical) neural network scheme...
متن کاملFast RLS Algorithms Running On Roughly Quantized Signals
A framework for obtaining fast RLS algorithms which use a roughly quantized auxiliary input signal for eeciently updating the required adaptation gain vector is presented. The new adaptation procedure is very similar to the conventional fast RLS adaptation. Analytically, it is shown that the lter weights are found by solving almost the same normal equations corresponding to the RLS case. Obtain...
متن کاملLossless Audio Coding Using a Cascaded Rls-lms Predictor
This paper introduces a cascade d RLS-LMS predictor for predictive lossless audio coding applications. In this proposed predictor, a LMS predictor with large order is employed in order to capture the ample tonal and harmonic components of the audio signal for optimal prediction gain performance. Meanwhile, to solve the slow convergence problem of the LMS algorithm with colored inputs, a low-ord...
متن کاملQr-rls Adaptation of Modular Multichannel Lattice Filters
This paper examines an extension of QR-RLS lattice filtering to the case of multiple input signals. The proposed adaptation algorithm is based on a compact square-root array formulation that is amenable to hardware implementation due to its scalar-only nature, parallelizability and numerical robustness. A technique that provides increased design flexibility by allowing unequal filter lengths to...
