    摘要: A VCO includes a transformer-based resonator that has a first LC tank and a second LC tank. The resonator has an even resonant mode and an odd resonant mode. The VCO further includes an active transconductance network that is coupled to a two-terminal port of the first tank and is also coupled to a two-terminal port of the second tank. A first terminal of the port of the first tank is capacitively coupled to a first terminal of the port of the second tank. A second terminal of the port of the first tank is capacitively coupled to a second terminal of the port of the second tank. The active transconductance network causes the resonator to resonate in a selectable one of the even and odd resonant modes depending on a digital control signal. The VCO is fine tuned by changing the capacitances of capacitors of the tanks.

    摘要: The present invention relates to the field of communication technologies and discloses a method, an apparatus, and a system for active-standby switchover. The method includes: copying at least one packet group to a standby board; recording the copied packet group and generating a transmission rule chain table of an active board according to a sequence of copying, so that the standby board generates a transmission rule chain table of the standby board which is the same as the active transmission rule chain according to the sequence of copying; and transmitting the packet group according to the sequence of the transmission rule chain table of the active board. By using the method, resuming transmission from a breakpoint upon an active-standby switchover is enabled.

    摘要: An improvement in a method of transmit beamforming between a transmitter (16) and a receiver (18) for a time varying lading channel comprises the step of performing transmit beamforming using less than complete knowledge of the previous fading blocks to design a codebook (26a) of a current fading block with each time frame. One embodiment comprises a successive beamforming algorithm and a second embodiment comprises a vector quantization beamforming algorithm. A fading parameter α is determined at least in the transmitter or receiver by monitoring a mobile Doppler frequency.

    摘要: A method, system and computer program product for managing the lifecycle of an object, where the lifecycle involves a plurality of states of the object, at least one transition between the plurality of states and at least one role who has authority to execute the at least one transition. At least one of the plurality of states, the at least one transition and the at least one role is mapped to Web Ontology Language (OWL) elements. The role related control information is obtained using the reasoning ability of OWL itself according to the above mapping. Furthermore, the lifecycle is managed according to the above role related control information. Using the principles of the present invention, the access control information of roles can be embedded into the lifecycle description and therefore the lifecycle management can be realized easily.
