Related to Perturbation: Perturbation theory

PERTURBATION. This is a technical word which signifies disturbance, or infringement of a right. It is usually applied to the disturbance of pews, or seats in a church. In the ecclesiastical courts actions for these disturbances are technically called "suits for perturbation of seat." 1 Phillim. 323. Vide Pew.

Analytical solutions for the transverse electric field distributions found for some basic dielectric profiles [mathematical expression not reproducible], such as rectangular slabs and cylindrical waveguides, can be used as basis solutions for finding analytical approaches of relatively more complex transverse dielectric distributions by using the perturbation theory [4-6]; this method allows spanning the perturbed scenario through a linear combination of the unperturbed solutions.
It is clear that the presence of small-scale perturbation in SLP (wind, vorticity, geopotential height, etc.) field has significant effect on correctly identifying the center of landed TC in a numerical model.
Therefore, considering the backbone HTS relaying communication undergoes the large-scale and complex SIN dual-hop channel properties, such as rain attenuation [7], solar scintillation [8], perturbation factors [9], and interference [10-13], this paper investigates the performance of SIN return channel cooperative communications via an amplify-and-forward (AF) backbone satellite relaying for VN communications.
