Microcell engineering in CDMA cellular networks

Abstract: The demand for cellular radio services is growing rapidly, and in heavily populated areas the need arises to shrink the cell sizes and "scale" the clustering pattern. The extension of the service into the PCN domain, mostly in-buildings and in pedestrian areas, further enhances this trend. The vision of the "third generation" cellular systems incorporates micro- and picocells for pedestrian use, with macrocells for roaming mobiles. Connectivity between all these cells, while maximizing total system capacity, is the main challenge facing the "third generation architects." The CDMA cellular system, which shares the same frequency channel across the system (reuse pattern of one) and applies soft handoff between the cells, has already shown, both by analysis and by tests, to have full connectivity between the microcells and the overlaying macrocells without capacity degradation. The parameters involved in the engineering of a heterogeneous CDMA network are discussed in the paper. Factors that determine the size of the cell, the soft handoff zone, and the capacity of the cell clusters are analyzed, and engineering techniques for overlay-underlay cell clustering are outlined. >

Coding motion depth maps with depth range variation

Abstract: This disclosure describes techniques for coding 3D video block units. In one example, a video encoder is configured to determine a first real-world depth range for a first depth view component comprising a reference view component, determine a second real-world depth range for a second depth view component comprising a current view component, wherein the current view component is predicted relative to the reference view component, determine a predictive block for a portion of the current view component from the reference view component, adjust values of the predictive block based on a difference between the first real-world depth range and the second real-world depth range, and predict the portion of the current view based on the adjusted values of the predictive block.

Integrated display and management of data objects based on social, temporal and spatial parameters

Abstract: An embodiment is directed to displaying information to a user of a communications device. The communications device receives a query including a social parameter, a temporal parameter and a spatial parameter relative to the user that are indicative of a desired visual representation of a set of data objects. The communications device determines degrees to which the social, temporal and spatial parameters of the query are related to each of the set of data objects in social, temporal and spatial dimensions, respectively. The communications device displaying a first visual representation of at least a portion of the set of data objects to the user based on whether the determined degrees of relation in the social dimension, temporal dimension and spatial dimension satisfy the respective parameters of the query.

System and method of managing displays at a portable computing device and a portable computing device docking station

Abstract: A method of managing a portable computing device (PCD) display and a PCD docking station display when a PCD is docked with a PCD docking station is disclosed and may include connecting a PCD data driver to the PCD docking station display, transmitting a primary display signal to the PCD docking station display, and transmitting a secondary display signal to the PCD display. The method may include displaying primary information at the PCD docking station display. The method may also include displaying secondary information at the PCD docking station display.

Antenna system for multipath diversity in an indoor microcellular communication system

Abstract: A system for mitigating the effect of fading in a digital communication system Deep signal nulls occur when signals from multiple paths are precisely aligned in amplitude and phase canceling the signal at the receiving antenna and creating a fade In an indoor system, moving either transmitter or receiver a short distance can shift a fade away from the frequency of interest This invention provides an actual or perceived movement of an antenna such that the effects of fading can be averaged over a time interval The signal processing capability of modern digital transceivers can correct errors due to the time varying fades using the present invention Thus, a dual-antenna element using the system of this invention can provide diversity receive and transmit paths to maintain capacity The present invention may also provide improved capacity to due enhanced stability in power control
