Simultaneous temporal and spatial processing

Spatial - Temporal Signal Processing

Among multi-access communications techniques, CDMA (Code Division Multiple Access) is interference-limited. Conventional single-user receivers su er from the nearfar problem in CDMA cellular communications systems. One method to suppress multi-access interference is digital beamforming by using base-station antenna arrays. However, using beamforming alone cannot solve the near-far problem. Verd...

Simultaneous processing of verbal and spatial information.

Two experiments investigated the generality of the selective interference phenomenon by studying several different concurrent tasks, each involving either verbal or spatial information, and a range of retention intervals from 10 to 30 sec. The results supported the selective interference predictions, since the interference in performance was greater when the two simultaneous tasks both involved...

Simultaneous Spatial and Temporal Focusing in Nonlinear Microscopy.

Simultaneous spatial and temporal focusing (SSTF), when combined with nonlinear microscopy, can improve the axial excitation confinement of wide-field and line-scanning imaging. Because two-photon excited fluorescence depends inversely on the pulse width of the excitation beam, SSTF decreases the background excitation of the sample outside of the focal volume by broadening the pulse width every...

Privacy Spatial and Temporal Distances in Nomadic Settelments

Human always in interaction with their social environment, have consider some degree of privacy with different purposes, for themselves, the people around them and carry out their activities. Creating privacy depends on two elements; subjective meanings that ruling the creation of privacy, and the second sentence are person available facilities. Privacy is not seen, heard, smelled and availabil...
