摘要： Transmission lines with a first dielectric material separating signal traces and a second dielectric material separating the signal traces from a ground plane. In embodiments, mutual capacitance is tuned relative to self-capacitance to reverse polarity of far end crosstalk between a victim and aggressor channel relative to that induced by other interconnect portions along the length of the channels, such as inductively coupled portions. In embodiments, a transmission line for a single-ended channel includes a material of a higher dielectric constant within the same routing plane as a microstrip or stripline conductor, and a material of a lower dielectric constant between the conductor and the ground plane(s). In embodiments, a transmission line for a differential pair includes a material of a lower dielectric constant within the same routing plane as a microstrip or stripline conductors, and a material of a higher dielectric constant between the conductors and the ground plane(s).

摘要： A road network is described using roads, intersections and sections as traffic information elements and a correspondence between these elements and a road topological network in a digital map is established, so that a universal traffic information describing model, which is compatible with language used in people's daily life, can be established. The traffic information element knowledge base is generated based on roads, intersections and sections, respective attributes and the relationship between them, to support inter-conversion between road topological network traffic information and text-based traffic information. With the universal traffic information describing model and the traffic information element knowledge base, fusion and conversion of traffic data from various sources and to support various forms of presentation and interaction for traffic information, such as presentation of traffic information on digital navigation map, textual description of traffic information, map presentation of traffic information for urban trunk roads, etc. can be supported.

The interposer has pins arrayed on a first side which are soldered to the package substrate for reduced interposer z-height and pads arrayed on a second side to which the top package (chip) is bonded. During assembly, the interposer pins may be pressed against pre-soldered pads and the solder reflowed to join the interposer to the package substrate. A top package (chip) is then joined to an opposite side of the interposer to integrate the first and second chips.

摘要： A system and method is proposed for adapting the spatial transmission strategy in a cellular MIMO (multiple input multiple output) communication system for the downlink. Spatial mode adaptation, the choice of multiplexing, transmit diversity, number of streams, space-time code family, and the like are performed slowly based on side information from other base stations. Base stations exchange their transmission plans with neighboring base stations and broadcast this information to active users. Each user measures its susceptibility to spatial interference and returns this information to the base station. The base station then schedules active users according to the decisions made in interfering base stations and the preferred transmission strategies of its own users.
