Abstract: 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.

Abstract: 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.

Abstract: A method and system for indicating a transmission parameter are provided in the present invention. The method includes: when multi-user multi-input multi-output (MIMO) data are transmitted, using a newly-added indication signaling in a downlink control information format to indicate different joint encoded parameters when numbers of enabled transport blocks are different. Through adding new indication signaling in the present invention, different joint encoded parameters are indicated during the multi-user MIMO data transmission and the MIMO multi-user transmission based on the demodulation reference signal is supported.

Abstract: 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.
