摘要： Path delays experienced by a received signal are estimated for use in, for example, a RAKE receiver. This involves hypothesizing a plurality of path delays. For each of a plurality of measurement time slots and for each of the hypothesized path delays, a measurement based on the received signal is made along with a determination of whether a fade occurred. For each of the plurality of measurement time slots and for each of the hypothesized path delays, the measurement is combined with a corresponding one of a plurality of cumulative metrics only if it was determined that no fade occurred. Then, for each of the plurality of hypothesized path delays, the corresponding one of the plurality of cumulative metrics is used to determine whether the hypothesized path delay corresponds to a real path delay.

摘要： The present invention relates to a method of assigning data from time slots on an input bus to time slots on an output bus comprised of determining the order of time slots of data in a frame, determining whether each time slot of data in an input frame is to be located in the same or later time slot in an output frame, or whether it is to be located in an earlier time slot in an output frame, in the event each time slot of data of the input frame is to be located in the same or later time slot in an output frame, applying each time slot of data of the input frame to the same or a later time slot in the output frame, in the event a time slot of data of the input frame is to be located in an earlier time slot in an output frame, delaying for one time slot internal and then applying each time slot of data of the input frame to the same or a later time slot in the output frame, whereby the order of time slots in a stream of output data is always from an earlier time slot to a later time slot.

摘要： An adaptive rate management method and system for adapting a receiver rate to a transmission rate in a packet switch network comprises determining an error value at a sample rate, obtaining an updated accumulator value based on said error value Es at a decimated sample rate, and generating an appropriate rate command and changing said accumulator value at the decimated rate based on the updated accumulator value. The method may be adapted for either adapter point management or bit stuffing. When applied to adapter point management (APM), the method generates pointer adjustments for rate management. In a frequency locked APM preferred embodiment of the method and system, pointer adjustments in an interval are generated at a constant rate based on an average pointer adjustment value calculated in previous intervals.

摘要： Normal 802.3 Ethernet requires a tree topology. If a ring or a loop exists, then packets will be forwarded around the ring indefinitely. If the ring is broken, then there is no possibility of packets being propagated forever. This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that handles a unidirectional break in a communication link. This abstract is provided as an aid to those performing prior art searches and not a limitation on the scope of the claims.

摘要： A digital switch includes a switching fabric that switches data between a plurality of ports. The switching fabric includes data lines and a control line. An arbitrator arbitrates traffic between the plurality of ports. A command processor receives a command over the control line and modifies a switching fabric parameter in response to the command. The control line is preferably the same line that is not used during normal switching fabric operation, such as, for example, an ABORT line, or ABORT pin.

摘要： A control network comprises multiple master nodes and multiple slave nodes, connected together in a loop configuration by at least one fiber optic cable. The master nodes share concurrent control over the network nodes by time multiplexing or other techniques. The control network may include two fiber optic rings which carry the same data simultaneously in opposite directions around the loop. A polling scheme may be used by the master nodes such that only one node transmits at a given time in both directions around the loop. The receiving node(s) propagate the transmissions and select between the transmissions based on time, error rate, or other factors. A hierarchical control network may be constructed with upper tier and lower tier fiber optic rings. Multiple master nodes may be used at any level of the ring, and some or all of the rings may include two fiber optics for bidirectional, redundant communication within the network.
