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 ...

Abstract One important use of the standard inner product of ℝ 3 is that it allows us to distinguish between ‘nice’ bases such as the usual one where the basis vectors are orthogonal to each other and each has length 1, and others such as (1, 0, 0)T, (1, 1, 0)T, (1, 1, 1)T where this is not true.

MDS codes based on orthogonality of quasigroups
Applicable Algebra in Engineering, Communication and Computing, 2023This paper presents a construction of maximum distance separable (MDS) codes through the use of orthogonal systems of \(k\)-ary quasigroup operations, including the concept of extended \(i\)-invertibility. The authors build on established results in quasigroup theory and multivariate polynomial systems to construct recursive linear MDS codes over ...

Local orthogonal bases I: Construction
Multidimensional Systems and Signal Processing, 1996The authors present a unified approach to the construction of local orthogonal bases in the continuous and discrete multivariate setting by using symmetry properties of basis functions. Examples for one- and two-dimensional, discrete and continuous cases are included.

An example of a basis for space C, close to the Schauder system, is constructed which, after orthogonalization by the Schmidt method, is not a basis for space LP for any p e [1, 2) +(2,∞].

Orthogonal hermite functions based orthogonal pulse shaping method
2009 Canadian Conference on Electrical and Computer Engineering, 2009Ultra-Wideband (UWB) communication has attracted more attentions due to its advantages in short range applications. As one of the key techniques in UWB systems, many pulse shaping methods have been proposed. The semi-definite programming (SDP) based pulse shaping method can obtain the pulse with highest power efficiency by far.
