Research on Subcarrier Weighting Technology Based on OFDM [PDF]

open access: yesJisuanji gongcheng, 2018
Based on the inherent high sidelobe problem in Orthogonal Frequency-Devision Multiplexing (OFDM) system,a sidelobe suppression method for OFDM system is proposed based on subcarrier weighting method.The subcarrier weights are determined in such a way ...

Constrained ultraspherical-weighted orthogonal polynomials on triangle

open access: yes, 2015
We construct Ultraspherical-weighted orthogonal polynomials C (λ,γ) n,r (u, v, w), λ > − 2 , γ > −1, on the triangular domain T, where 2λ + γ = 1. We show C (λ,γ) n,r (u, v, w), r = 0, 1, . . .

Diffusion along perivascular spaces reveals evidence supportive of glymphatic function impairment in Parkinson disease

open access: yesParkinsonism & Related Disorders, 2021
Background: Reduced diffusion along perivascular spaces in adults with Alzheimer’s-disease-related-dementias has been reported and attributed to reduced glymphatic function. Objectives: To apply quantitative measures of diffusion along, and orthogonal to,

Fully probabilistic seismic source inversion – Part 1: Efficient parameterisation [PDF]

open access: yesSolid Earth, 2014
Seismic source inversion is a non-linear problem in seismology where not just the earthquake parameters themselves but also estimates of their uncertainties are of great practical importance.

CONSTRUCTION OF TCHEBYSHEV-II WEIGHTED ORTHOGONAL POLYNOMIALS ON TRIANGULAR

open access: yes, 2015
We construct Tchebyshev-II (second kind) weighted orthogonal polynomials U (γ) n,r (u, v, w), γ > −1, on the triangular domain T. We show that U (γ) n,r (u, v, w), n = 0, 1, 2, . . . , r = 0, 1, . . . , n, form an orthogonal system over T with respect to

A Binary Orthogonal Chirp Signal Modulation Method with Delay Offset [PDF]

open access: yesJisuanji gongcheng, 2017
In the case of low Time-Bandwidth(TB) product,there are two problems in the Binary Orthogonal Keying(BOK) matching detection,the mutual interference between the positive and negative frequency modulation slope and the large amplitude of the self-matching
