摘要： Embodiments include processes, systems, and devices for reshaping virtual baseband signals for transmission on non-contiguous and variable portions of a physical baseband, such as a white space frequency band. In the transmission path, a spectrum virtualization layer maps a plurality of frequency components derived from a transmission symbol produced by a physical layer protocol to sub-carriers of the allocated physical frequency band. The spectrum virtualization layer then outputs a time-domain signal derived from the mapped frequency components. In the receive path, a time-domain signal received on the physical baseband is reshaped by the virtual spectrum layer in order to recompose a time-domain symbol in the virtual baseband.

摘要： An extended wireless access point may have many distributed radio units connected to associated processing units via a radio transmission network comprising commodity switches controlled by one or more network controllers. The one or more network controllers may use a load balancing algorithm to select a processing unit to process a signal received by a distributed radio unit. The radio units may receive a wireless signal, and generate compressed samples of the wireless signal for transport via the radio transmission network and processing by a selected processing unit. Similarly, a processing unit may generate and transmit via the radio transmission network compressed samples for decompression and transmission by a radio unit.

摘要： Implementations for retransmitting erroneous portions within a transmission frame are described. A sender transmits a transmission frame and the receiver performs error detection on portions of the transmission frame in order to determine if any are received in error. The receiver sets up a feedback channel and transmits acknowledgements to the receiver to indicate that one or more portions have been received and to identify any portions that are received with errors. At least some of the acknowledgements are transmitted prior to receipt of the entire transmission frame. The sender retransmits any portions that are identified as being erroneous within the transmission frame.

摘要： An extensive use of look-up table (LUT) and single instruction multiple data (SIMD) in different algorithms in a software-defined radio (SDR) system is described. In particular, the LUT is used during spreading modulation, mapping and spreading, scrambling, de-scrambling, soft demapping, and the like. The SIMD is executed by a multi-core processor during implementation of a “min” operation to find an optimal path in a Trellis diagram for a Viterbi decoder.

摘要： Various exemplary user interfaces, methods and computer program products describe enabling sharing of mobile communication devices. This process utilizes a shared mode for an owner of the mobile communication device to create a virtual environment for a borrower of the mobile communication device, which allows content information (e.g., certain applications and files) to be accessible and visual to the borrower. The process allows an owner of the mobile communication device to track and to manage data created or changed by the borrower. The owner may accept or reject the changes made in the content information. Furthermore, the process conceals non-shared resources to the borrower.

摘要： A method and system for providing a multi-level interconnection network is provided. A multi-level interconnection network comprises basic cells that are aggregated into higher level cells at each level of the network. At the first level, the basic cells are aggregated into first level cells. Each first level cell is an aggregation of a number of basic cells that is one more than the number of devices in a basic cell. The basic cells of a first level cell are fully connected; that is, each basic cell has a first level link or connection to each other basic cell. In a first level cell, each device of a basic cell has a first level link to each other basic cell. The multi-level interconnection network has higher level cells that are aggregations of lower level cells in a similar manner.

摘要： A number of data center units in a data center system may be directly connected with each other via switch interfaces. The data center system is server-centric and scalable by storing routing logics (e.g., inter-data center unit logic and/or inner-data center unit logic) at each server to achieve routing, load balancing, and/or fault tolerance. Switch interfaces of the data center units, thus, may be dumb devices and a centralized router for routing data among data center units may be omitted.
摘要翻译：数据中心系统中的多个数据中心单元可以通过交换接口直接相连。通过在每个服务器处存储路由逻辑（例如，数据间中心单元逻辑和/或内部数据中心单元逻辑）来实现路由，负载平衡和/或容错，数据中心系统是以服务器为中心和可扩展的。因此，数据中心单元的切换接口可以是哑设备，并且可以省略用于在数据中心单元之间路由数据的集中式路由器。
