We examine site selection diversity transmission (SSDT) for 3GPP WCDMA forward link by means of analytical tools. Hard handover (HHO), soft handover (SHO) and SSDT are compared by using the receiver bit error probability as a performance measure taking into account the effect of feedback bit errors as well as the shadow fading. Results show that without fast transmission power control the perfo...

Abstract In this paper, it is theoretically shown that the optimal solution to maximize the DS-CDMA forward link capacity under the condition of constant total transmit power is to transmit only from the best base station (BS) that has the maximum channel gain (this is called site selection diversity transmit (SSDT)). This theoretical analysis is confirmed by the Monte-Carlo computer simulation...

OBJECTIVE The Somatic Signal Detection Task (SSDT; Lloyd, Manson, Brown and Poliakoff, 2008) is an innovative paradigm to study perceptual processes related to physical symptoms. It allows examining touch illusions as a laboratory analog of medically unexplained symptoms (MUS) according to the cognitive model of MUS proposed by Brown (2004). The present study compared psychopathologic measures ...

In this paper, the static and free vibration analysis of laminated shells is performed by radial basis functions collocation, according to a sinusoidal shear deformation theory (SSDT). The SSDT theory accounts for through-the-thickness deformation, by considering a sinusoidal evolution of all displacements with the thickness coordinate. The equations of motion and the boundary conditions are ob...

We have previously found that attention to internal somatic sensations (interoceptive attention) during a heart beat perception task increases the misperception of external touch on a somatic signal detection task (SSDT), during which healthy participants erroneously report feeling near-threshold vibrations presented to their fingertip in the absence of a stimulus. However, it has been suggeste...

Evidence suggests that interoceptive and exteroceptive attention might have different perceptual effects. However, the effects of these different types of body-focused attention have never been directly compared. The current research investigated how interoceptive and exteroceptive attention affect subsequent performance on the somatic signal detection task (SSDT). In Experiment 1, 37 participa...

The Somatic Signal Detection Task (SSDT) is a recent paradigm serving to examine perceptual processes likely relevant for somatoform disorders. We tested whether touch illusions are more easily induced in individuals suffering from somatoform disorders (SFD) and whether their perceptual threshold for tactile stimuli is lower compared to healthy controls. Thirty-three participants with SFD and 3...

Handoff in heterogeneous cellular networks is one of the hot topics for wireless networks beyond the third generation. We observe that a power exhausting issue may occur in a code division multiple access (CDMA) system with mixed-sized cells. During soft handoff in the downlink transmission, a number of base stations transmit signals to a user simultaneously. Usually, a microcell has a more str...

In this paper, a new power control scheme is proposed for optimizing the power division between the BSs in the active set during soft handover. In stead of splitting the power equally between the BSs in the active set, it controls the power division according to the propagation attenuation of each radio channel. The optimized power control minimizes the interference and maintains getting benefi...

Coronavirus disease (COVID-19) is an infectious caused by the SARS-CoV-2 virus and population vulnerability increased all over world due to lack of effective remedial measures. Nowadays vaccines are available; but in India, only 18.8% has been fully vaccinated till now. Therefore, social distancing precautionary norm avoid spreading this deadly virus. The risk spread can be avoided adhering nor...
