    摘要: An off-chip signal is provided to a differential branch-line directional coupler implemented entirely on-chip. The coupler produces differential quadrature signals, which are then buffered and applied to a quadrature mixer. The coupler is implemented entirely on-chip using microstrip transmission lines. The coupler is made up of a plurality of rings and a plurality of underpasses connecting ports of the rings, wherein each of the plurality of rings is made up of four branch lines, and each branch line having an electrical length of one-quarter wavelength at the center design frequency. Coupling between the plurality of branch lines of the rings may be varied.

    摘要: An apparatus and method to control signal phase in a radio device includes a phase rotator configured to control a phase of a local oscillator. A phase error determination module is configured to determine phase error information based on received in-phase (I) and quadrature (Q) (IQ) signal values. A phase correction module is configured to derive from the received IQ signal values a correction signal and apply the correction signal to the phase rotator in a path of the local oscillator.

    摘要: Methods and apparatus to support dynamic allocation of traffic management resources in a network element. Shared pools of traffic management resources comprising an aggregation of local line card resources distributed across the line cards or a network element maintained by apparatus software. Incoming packets are classified into subscriber flows using a hierarchical classification scheme. In view of subscriber services and flow application types, traffic management resources are dynamically allocated from the shared pools, and traffic management policies associated with the subscriber services and application types are applied to the subscriber flows via the allocated resources. In response to detecting a subscriber flow has terminated, the allocated resources are release and made available to be dynamically re-allocated to subsequent subscriber flows.

    摘要: A system for generating a sequence of learning objects comprising an e-Learning course is provided. The system can include one or more processors and a memory unit for electronically storing data comprising a plurality of learning objects. The system further can include a sequence builder configured to execute on the at least one processor. The sequence builder, more particularly, can be configured to generate a sequence comprising at least a portion of the plurality of learning objects based upon a measurable user relevancy and/or a measurable query relevancy of each learning object contained in the sequence.
