A service convergence fabric () is operably disposed between a plurality of independent access networks, control networks, and service networks () and a converged application layer (). This service convergence fabric is then used () to receive a service request, process the service request, provide a corresponding response, and publish that response to facilitate the service request. Processing the service request can comprise processing the service request with respect to resources to support the service request, user session status as corresponds to the service request, and user preferences as correspond to the service request. Providing a response can comprise providing a response that comprises at least one of a processed service request and a converged response to the service request.

Method and apparatus regarding use of a service convergence fabric

In a cable television system a system for supporting SCU return in FTTB-MDU and FTTC/FTTcab configurations. Fiber, baseband transceiver and networking capabilities are shared with data and voice portions of the system for enabling communication from the SCUs to the HE over a packet based networking system. Return packets/upstream packets are passed into the network upstream channel only when a signal is present for eliminating transmission of upstream traffic that contains no signal for conserving upstream bandwidth.

First location information related to a location-aware device () is gathered. Second location information for a location-unaware device () is determined from the first location information. A data structure is created comprising a binding of the second location information and an identifying parameter of the location-unaware device (). The data structure is provided in a form usable by an application.

A method and apparatus for automated correlation of digital modulation impairment is described. The technique obtains soft decision data () and extracts signal space location information of sufficient resolution to distinguish different types of impairment to a digitally modulated signal. The technique applies an error vector magnitude mask () and determines the signal-to-noise ratio of the digitally modulated signal. The technique applies impairment masks () and provides a characterization () of impairment affecting the digitally modulated signal (). The technique determines a subset of the soft decision data () that falls within the impairment masks () and calculates correlation weights (). The technique may be used to identify, isolate, and classify different types of impairment. Given sufficient data collection, sources of impairments may be determined precisely.

The present invention is a method and system for extracting information from a received signal with minimal loss due to noise. The system comprises of a transformer, for correlating the received signal to a wavelet function and producing wavelet decomposition coefficients, and a threshold circuit, which is responsive to the received signal, for applying predetermined threshold values based on the type of signal. Also included in the system is a filter, coupled to the transformer and threshold circuit, for altering the wavelet decomposition coefficients produced by the transformer using threshold values applied by the threshold circuit to produce altered wavelet coefficients from which the received signal is reconstructed with reduced noise.

A direct down conversion receiver includes a signal filter having a selectable frequency response for receiving an input signal. The filtered signal is amplified by a variable gain amplifier, and the amplified signal is received as input by an analog-to-digital converter. The analog-to-digital converter generates a series of digital samples representative of the filtered signal. A controller measures a corresponding peaking ratio of the filtered signal from the series of digital samples for each of a plurality of frequency bands and selects the frequency response of the signal filter as a function of the measured peaking ratios. The signal filter may include an adjustable highpass filter and an adjustable lowpass filter. The cutoff frequency of the lowpass filter and the cutoff frequency of the highpass filter are selected to attenuate the level of the input signal in one or more of the plurality of frequency bands so that the signal presented to the analog-to-digital converter has a peaking ratio approximately equal to a selected peaking ratio threshold across the frequency range of the input signal.

A method, and apparatus for performing the method, the method consists of the steps of: estimating a time when a dominant channel distortion occurs for each of a plurality of received test signals, wherein each of the plurality of received test signals occupies a different position in frequency in a communications medium having a given bandwidth; determining a differential group delay for the times estimated for each of the plurality of received test signals; and approximating a phase distortion of the communications medium as the differential group delay. In a variation, the method further consists of the steps of: estimating a power of each of the plurality of received test signals; determining an amplitude ripple by evaluating the power of each of the plurality of received test signals; and approximating an amplitude distortion of the communications medium as the amplitude ripple.

A first mixer (306) shifts a first end (208) of a desired signal frequency bandwidth (206) of a desired signal (202) to an edge (508) of a first filter frequency bandwidth (502) of a first filter (312), wherein the first filter frequency bandwidth (502) is greater than the desired signal frequency bandwidth (206). Signals within a first undesired frequency spectrum (504) are attenuated by the first filter (314). A second mixer (316) shifts a second end (210) of the desired signal frequency bandwidth (206) to an edge (608) of a second filter frequency bandwidth (602) of a second filter (320) to receive the desired signal (202).
