This invention relates to cognitive radio based wireless communications of dynamic spectrum access networks, and in particular to a method of addressing zero-delay frequency switching for cognitive dynamic frequency hopping. The method combines regular (periodic) channel maintenance with dynamic frequency hopping over a cluster of vacated channels that are initially setup such that the switching delays for channel setup and channel availability check are eliminated.

The invention discloses a method, a receiver and a wireless terminal for measuring an impulse response e.g. in a (W)CDMA terminal having at least two receiving antenna branches with diversity reception. In the method one antenna branch is selected, e.g. by choosing the antenna with a good signal to interference ratio. An impulse response is measured for the selected antenna branch (full IRM) with a searcher. The delays of the propagation paths of the radio channel are estimated by selecting the delay values, whose correlation value exceed a threshold value. The impulse response measurement for the other antenna branch is performed only on the selected delay values (reduced IRM) with the searcher. The finger allocation for the selected antenna branch can be done immediately after the full IRM and for the other antenna immediately after the reduced IRM. The finger allocation for all branches can alternatively take place after the reduced IRM, simultaneously. The invention may be implemented in at least one of a programmable device, dedicated hardware, programmable logic and any other processing device.

The present invention provides a means for managing title keys by establishing logical partitions of title keys encrypted with the same binding information.

The cost function includes an item that minimizes usage of the second-level routing matrix (22) that connects between the segments.

A system and method for self-diagnosing a likely cause of a system crash is disclosed. A mechanism within an operating system checks for the existence of a stop code at startup of the machine. The existence of the stop code indicates that the system crashed during the previous session, and the type of system crash. The mechanism may read the stop code and implement a self-diagnostic procedure that corresponds to that stop code. In this manner, the mechanism may automate many of the tasks normally performed by humans, such as a system administrator, to self-diagnose the likely cause of the crash. If the crash occurs again, the mechanism, through the tracking procedures automatically implemented, may identify and report to a system administrator the likely cause of the crash, e.g. the particular faulty driver or configuration error.

A computer system is structured, including a plurality of computers sharing a storage apparatus. The computers each include a control section for determining an access priority based on an attribute of a client computer forwarding an access request. In the control section, the result derived by adding up the priorities is compared with the total value of the priorities calculated by other computers for assignment of an input / output bandwidth. In accordance with the priority assignment, access execution is performed in order of priority. With such a structure, access congestions can be favorably avoided through efficient bandwidth control, and bandwidth assignment can be performed on a server basis in accordance with processes executed by the client computers.

A mechanism for optimizing an establishment of a communication connection between a mobile node and a correspondent node in a packet based communication network using, for example, IP is proposed. After starting an application level communication connection setup, for example SIP based, between the mobile node and the correspondent node via a communication subsystem infrastructure, for example the IM subsystem infrastructure, a trigger signal comprising the address of the correspondent node is transmitted from the SIP layer to the IP layer in the mobile node via an interface. In response to the trigger signal, an IP level route optimization procedure is performed while the application level communication connection setup proceeds.

A switched meander line structure is substituted for a lumped element coupler (10) for an order of magnitude increase in gain due to the use of the switched meander line architecture. The use of the meander line (20) with relatively wide and thick folded legs markedly decreases I2R losses over wire inductors whose wire diameters at one-tenth of an inch contribute significantly to I2R losses. Additionally, placing solid state switches to short out various sections of a multi-leg meander line at high impedance nodes reduces I2R losses across the switching elements in the coupler. It has been found that, regardless of the impedance of the antenna, this impedance may be matched by switching in and out various sections of a folded multileg meander line due to the fact that the square of the sum of the capacitive reactances of the meander line decreases with frequency in synchronism with the unloaded Q of the meander line, thus to provide the ability to maintain a good match over frequency as the meander line is tuned to achieve resonance by shorting out combinations of sections of the meander line. The result of the substitution of the meander line architecture for the lumped element coupler is the reduction of losses associated with the use of wire inductors and losses due to the interposition of solid state switches at high-current nodes.

An improved streaming of a Virtual Reality [VR] video to a VR rendering device is provided. The VR video may be represented by a plurality of streams each associated with a different view of a scene. A view of the scene may be determined which is to be rendered by the VR rendering device. A subset of streams may be identified which is needed to render the view of the scene. The streaming of the subset of streams to the VR rendering device may be effected by streaming the plurality of streams from a stream source to a forwarding node downstream of the stream sources and upstream of the VR rendering device, and selectively forwarding the subset of streams from the forwarding node to the VR rendering device in response to the view having to be rendered by the VR rendering device. As such, the switching latency between streams may be reduced. Namely, streams which are not needed for rendering a current view, but which may be needed for rendering a next view, may be continuously made available at network nodes nearby the VR rendering device.

There is provided a controller for a converter and a respective method of operating such a controller. The converter receives an input power and provides an output power by a switching operation wherein in an embodiment the output power has at least two phases. The controller includes an input for receiving a feedback signal depending on the output power of the converter, and an output for providing a control signal to the converter to thereby control the switching operation of the converter. The control signal corresponds to a switching pattern that is updated in response to the feedback signal. The control signal includes a harmonic compensation signal which reduces higher harmonics in the output power, the higher harmonics originating from a time delay between taking the feedback signal and the updating of the switching pattern.

Embodiments disclosed herein include vector processing carry-save accumulators employing redundant carry-save format to reduce carry propagation. The multi-mode vector processing carry-save accumulators employing redundant carry-save format can be provided in a vector processing engine (VPE) to perform vector accumulation operations. Related vector processors, systems, and methods are also disclosed. The accumulator blocks are configured as carry-save accumulator structures. The accumulator blocks are configured to accumulate in redundant carry-save format so that carrys and saves are accumulated and saved without the need to provide a carry propagation path and a carry propagation add operation during each step of accumulation. A carry propagate adder is only required to propagate the accumulated carry once at the end of the accumulation. In this manner, power consumption and gate delay associated with performing a carry propagation add operation during each step of accumulation in the accumulator blocks is reduced or eliminated.
