Discrete-time cosine modulated filter banks, or modulated lapped transforms (MLT), have been in use for some time. Due to a few of their properties, they have become quite popular. For example, all filters (basis functions) of a filter bank are obtained by appropriate modulation of a single prototype filter.

On Orthogonal Coding-Based Modulation
IEEE Communications Letters, 2020In this letter, we propose a new orthogonal coding-based modulation (OCBM) scheme, in which all available transmitting subcarriers and antennas are activated at a time instant to transmit the data constellation symbols, and the indices of the activated subcarriers and antennas are also harnessed to carry information bits.

A novel orthogonal PSO algorithm based on orthogonal diagonalization
Swarm and Evolutionary Computation, 2018Abstract One of the major drawbacks of the global particle swarm optimization (GPSO) algorithm is zigzagging of the direction of search that leads to premature convergence by falling into local minima. In this paper, a new algorithm named orthogonal PSO (OPSO) algorithm is proposed that not only alleviates the associated problems in GPSO algorithm ...

Squeezable Orthogonal Bases: Accuracy and Smoothness [PDF]
SIAM Journal on Numerical Analysis, 2002 In this paper, the authors present a method for generating local orthogonal bases on arbitrary partitions on \(\mathbb{R}\) from a given local orthogonal shift-invariant basis via a so-called squeeze map. Necessary and sufficient conditions for a squeeze map are given to generate a nonuniform basis that preserves any smoothness and/or accuracy (i.e ...
