Enhanced interference management in heterogeneous wireless networks
We show that for any given muting fraction, a more constrained version of the problem of interest can be optimally solved in an efficient manner. In addition, the obtained solution is also a near-optimal solution for the original problem (for the given muting ratio). This allows us provide an algorithm that offers a good solution to the original problem with a tractable complexity. We also derive a lower complexity greedy that offers good performance and a certain worst-case performance guarantee. Simulations over an example LTE HetNet topology reveal the superior performance of the proposed algorithms and underscore the benefits of jointly exploiting partial muting of the macro and load balancing. |

Embodiments of the present invention provide an approach for a broker-assisted, publisher side cache that can be utilized to reduce a volume of data (e.g., network traffic) delivered between a publisher and broker in a publication/subscription (pub/sub) environment. Specifically, in a typical embodiment, when a message is received on a broker system from a publisher system, the broker system analyzes the message for potentially repetitive data. Such data can be determined from historical messages (e.g., determining that a certain set of data appeared in multiple messages and is thus flagged in a database or the like), a set of rules (e.g., if data set “Y” appears, flag it as potentially repetitive), etc. Regardless, once such a set of data has been identified, a unique identifier/key corresponding thereto will be sent back to the publisher system and the set of data will be stored in a (data) cache. Upon receipt, the publisher system will cache/store the unique identifier in a (key) cache. Then, when the publisher system generates a future message that would contain the same set of data, the publisher system will substitute the unique identifier (as retrieved from the key cache) for the set of data to yield an abbreviated/truncated message. The abbreviated message would be sent to the broker system, which would: analyze the message; locate the unique identifier; retrieve the corresponding set of data from the (data) cache; replace the unique identifier with the set of data to yield a completed message; and then send the completed message to relevant subscriber system(s). |

Determining a representation of an electrical signal
The invention relates to a method, systems, computer program, and computer-readable medium for reducing artefacts (speckling) which may appear to be noise/errors in a representation of an electrical signal. An Eye Pattern representation of a digital bit stream signal can be used for determining a range of signal quality characteristics, and can be generated from measurements of the proportion of ones and zeroes detected when sampling the signal at both at a reference data sampling position within a bit period and at a range of offset sampling positions.

While speckling may be reduced by increasing the sampling frequency used to sample the signal, the present invention reduces speckling by using data gathered at the reference data sampling point to correct data gathered at each of the offset sampling positions. Thereby, the invention reduces the number of samples needed in order to reduce speckling to a particular level. |
