M-ary orthogonal signaling in the presence of Doppler
IEEE Transactions on Communications, 1993The performance degradation of an M-ary orthogonal keying (MOK) system due to relative motion between its transmitter and receiver can be minimized by selecting good signaling sets. A formulation for evaluating good signaling sets, or code sets, is developed for Walsh function data modulations.

Improved Piecewise Orthogonal Signal Correction Algorithm
Applied Spectroscopy, 2003Piecewise 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.

New discrete orthogonal moments for signal analysis
Signal Processing, 2017Abstract The paper addresses some computational aspects and applications of the polynomial unbiased finite impulse response functions originally derived by Shmaliy as a new class of a one-parameter family of discrete orthogonal polynomials. We present two new explicit formulas to compute these polynomials directly.

A least-squares approach was used to construct near-orthogonal signals that can be useful in sonar applications. For the matched-filter case the solution can be written with Lagrange multiplier terms, which reduces to a simple eigenvector problem. Decoding filters are also examined, and these results are compared to the matched-filter case.

'Complementary' Signals and Orthogonalized Exponentials
IRE Transactions on Circuit Theory, 1962When a signal is approximated by a finite set of component signals which span a subspace \Phi , the least-square approximation may be interpreted geometrically in signal space as the projection of the true signal vector upon this finite dimensional subspace.

Optimum orthogonal quantization of signal space (Corresp.)
IEEE Transactions on Information Theory, 1978Orthogonal quantization is a partition of signal space that is achieved by independent quantization of each of its M orthogonal axes. A closed form expression is derived for the quantized channel cutoff rate and for the optimum orthogonal quantization similar to the one that has been derived for binary signaling.

Performance of Percent Gaussian Orthogonal Signaling Waveforms
2014 IEEE Military Communications Conference, 2014Recent developments of secure digital chaotic spread spectrum communication systems have been based on the generalized ideals of maximum channel capacity and maximal entropy/security, which result in a Gaussian-distributed noise like signal that is indistinguishable from naturally occurring (band limited) thermal noise.

Adaptive multirate signal estimation with lattice orthogonalization
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009In this paper, we address the signal estimation problem in statistical multirate systems. We propose an adaptive least squares lattice filter which is sequential and periodically time varying (PTV) with the multirate system period. Furthermore, we consider the elimination of redundant mathematical operations due to sequential processing of multirate ...

An orthogonal peak detector for multiphase sinusoidal signals
IEEE Transactions on Instrumentation and Measurement, 2000A novel sinusoidal amplitude detector is proposed. This detector is based on the characteristic of orthogonal pairs. The salient point of this algorithm is that it can be applied in multiphase systems. The transient performance of this detector is very good, due to its fast response characteristic.
