This paper provides the framework for the design of downlink admission control algorithms in the FDD mode of UMTS. Such algorithms are responsible of accepting or refusing requests of new connections depending on the resource availability in the downlink direction, which is measured in terms of the power and the amount of OVSF codes required by all the existing connections. So a specific algori...

1. Abstract At #6 Hannover meeting, we proposed inter-frequency measurement patterns for UTRA-FDD to UTRA-FDD cell search. Although all compressed mode patterns for IFHO is moved to informative Annex in RAN1#7bis meeting, the information about the performance using certain pattern is very useful to consider IFHO especially for UTRA FDD to UTRA FDD patterns that has not been reported. This docum...

Abstract This paper investigates the problem of incipient fault detection and diagnosis (FDD) in wind energy conversion systems (WECS) using an innovative effective approach called ensemble learning-sine cosine optimization algorithm (EL-SCOA). The evolved strategy involves two primary steps: first, a sine-cosine is used to extract optimize features order only select most descriptive ones. Seco...

This paper presents an applicable procedure for Fault Detection and Diagnosis (FDD) in a realistic nonlinear six degree-of-freedom unmanned aerial vehicle (UAV) model. The work has been developed based on the Matlab/Simulink environment of the NASA Generic Transport Model (GTM) UAV under the NASA Aviation Safety Program (AvSP). By introducing the partial loss fault in aircraft actuators into th...

In this paper two modal identification approaches appropriate for use in a distributed computing environment are applied to a full-scale, complex structure. The natural excitation technique (NExT) is used in conjunction with a condensed eigensystem realization algorithm (ERA), and the frequency domain decomposition with peak-picking (FDD-PP) are both applied to sensor data acquired from a 57.5-...

We investigate various array combining algorithms considering the special requirements of the UTRA/FDD uplink. After formulating the algorithms, we assess their performance in a modified vehicular B channel that is spatially inhomogeneous. The bit error ratios in different situations are presented together with some considerations about the computational complexity of the used methods. From bit...

A base station scanner that can evaluate MIMO antennas for LTE downlink signaling has been proposed. In this system, all signal processing is done offline, so analysis significantly delayed. Further, only FDD-LTE supported. This report details a coherent offers real-time demodulation of not FDD but also TDD. Experiments on signals using both duplex modes confirm the developed excellent performa...

Telecommunication companies have received a great deal of research attention, which have many advantages such as low cost, higher qualification, simple installation and maintenance, and high reliability. However, the using of technical maintenance approaches in Telecommunication companies could improve system reliability and users' satisfaction from Asymmetric digital subscriber line (ADSL) ser...

We calculate the ratio fBs/fBd by following the Oakes’ method which is based on chiral symmetry breaking, but we improve his calculation by performing the calculation of the factor < 0|b̄γ5s|Bs >/< 0|b̄γ5d|Bd > in the mock meson model. In this calculation we improved the mock meson model by using the value of the parameter β which is obtained by the variational method in the relativistic quark mo...
