Improved Piecewise Orthogonal Signal Correction Algorithm

Applied Spectroscopy, 2003
Piecewise orthogonal signal correction (POSC), an algorithm that performs local orthogonal filtering, was recently developed to process spectral signals. POSC was shown to improve partial least-squares regression models over models built with conventional OSC.

Piecewise orthogonal signal correction

Chemometrics and Intelligent Laboratory Systems, 2002
Abstract A novel signal-processing method that performs orthogonal signal correction (OSC) in a piecewise manner, namely piecewise OSC (POSC), is developed and applied to two near-infrared (NIR) data sets of multivariate calibration. Partial least squares (PLS) regression models were constructed for the POSC-corrected spectra, and the results were ...

Intersymbol Interference with Orthogonal Signaling

IEEE Transactions on Communications, 1975
The occurrence of both inter- and intrasymbol interference in a communications system utilizing orthogonal signals and memoryless correlation detection is described, and a system model is presented. A relationship between a bound on peak interference and time-bandwidth product for several well known orthogonal signal sets is reported.

Orthogonal Signals and the Orthogonalization Procedure

2021
Abstract Chapter 2 is dedicated to the principle of signal orthogonalization, because orthogonal signals are widely used in telecommunication theory and practice, like the carriers of baseband signals, subcarriers in orthogonal frequency division multiplexing systems, and the spreading sequences in spread-spectrum and code division ...

Orthogonal transforms for digital signal processing

ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1975
A tutorial-review paper on discrete orthogonal transforms and their applications in digital signal and image (both monochrome and color) processing is presented. Various transforms such as discrete Fourier, discrete cosine, Walsh-Hadamard, slant, Haar, discrete linear basis, Hadamard-Haar, rapid, lower triangular, generalized Haar, slant Haar and ...

Signal Orthogonal Transforms

2021
In this chapter we learn about orthogonal signal decomposition into a sum of weighted orthogonal functions (decomposition basis) like in Fourier series analysis. The decomposition weights are found by orthogonal transformation of signal samples, i.e. by multiplying them by rectangular orthogonal matrix having complex-conjugated decomposition functions ...

Signal identification based on orthogonal transform

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
A new approach to the identification of a constant amplitude signal with frequency/phase modulation is investigated. The authors model the incoming signal phase as a linear combination of a set of orthogonal vectors and use the significant coefficients as features for identification.

Adaptive orthogonalization of opponent-color signals

Biological Cybernetics, 1993
This paper concerns the processing of the outputs of the two opponent-color mechanisms in the human visual system. We present experimental evidence that opponent-color signals interact after joint modulation even though they are essentially independent under neutral steady adaptation and after exclusive modulation of each mechanism.

A new orthogonal transform for signal coding

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1988
The authors propose an orthogonal, unitary transformation called the modified Hermite transformation (MHT) and its extension, which is called the modular modified Hermite transformation (MMHT). The MHT algorithm, which is an efficient algorithm, is explained and explored.
