    摘要: Methods and apparatus for providing enhanced optical networking service and performance which are particularly advantageous in terms of low cost and use of existing infrastructure, access control techniques, and components. In the exemplary embodiment, current widespread deployment and associated low cost of Ethernet-based systems are leveraged through use of an Ethernet CSMA/CD MAC in the optical domain on a passive optical network (PON) system. Additionally, local networking services are optionally provided to the network units on the PON since each local receiver can receive signals from all other users. An improved symmetric coupler arrangement provides the foregoing functionality at low cost. The improved system architecture also allows for fiber failure protection which is readily implemented at low cost and with minimal modification.

    摘要: Disclosed are a method for transmitting feedback of channel state information and user equipment. The method comprises: under a transmission mode, user equipment (UE) determining contents carried by channel state information according to indication information, wherein the indication information comprises at least one of the following: rank indicator (RI), channel quality indication information (CQI) and configuration signaling sent by a base station eNodeB; and the UE sending the channel state information to the eNodeB.

    摘要: A method and apparatus for dynamically balancing traffic loads in a communications system (such as satellite communications systems), based on a control of collision rates via the real-time control of throughput of channels of the communications system (such as a real time throughput of random access channels in a satellite network). The method and apparatus generates and transmits to remote nodes or terminals an operating probability based on the determined throughput for transmission using the communications channel. Also, the method and apparatus includes receiving by at least one terminal the generated operating probability and determining by the at least one terminal a transmission probability for the communications channel based upon the received operating probability, which can further be adjusted by one or more of a received upper or lower limit of the generated operating probability or a collision rate for the communications channel.

    摘要: Electronic documents are retrieved from a database and/or from a network of servers. The documents are topic modeled in accordance with a Regularized Latent Semantic Indexing approach. The Regularized Latent Semantic Indexing approach may allow an equation involving an approximation of a term-document matrix to be solved in parallel by multiple calculating units. The equation may include terms that are regularized via either l1 norm and/or via l2 norm. The Regularized Latent Semantic Indexing approach may be applied to a set, or a fixed number, of documents such that the set of documents is topic modeled. Alternatively, the Regularized Latent Semantic Indexing approach may be applied to a variable number of documents such that, over time, the variable of number of documents is topic modeled.

    摘要: Systems and methods are provided for implementing error identification and evaluation for a Reed-Solomon (RS) error-correction code (ECC) system. The BMA algorithm and/or list decoding may produce one or more error locator polynomials that are related to a decision-codeword. An accelerated Chien search can be used to more quickly evaluate the one or more error locator polynomial. If the accelerated Chien search identifies a valid error locator polynomial, a normal Chien search can be used to identify error locations, and Forney's algorithm or an equivalent technique can be used to evaluate the error values. A RS ECC decoder can include a computation circuit that evaluates an error locator polynomial or an error evaluator polynomial. The computation circuit can include computation components that receive the coefficients of the polynomials.
