    Abstract: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one station, at least one access point, and at least one non-cooperative transmission source. The method includes steps of generating a matrix of each instance of request-to-send (RTS) messages received by the access point during a specified observation cycle, recording, in a memory of the access point, a number of cumulative RTS messages received from the station, calculating a cumulative distribution function (CDF), based on the recorded RTS message instances in the memory, for a probability of the presence of an aggressive transmission signal by the non-cooperative transmission source within a transmission range of the access point, and determining the presence of the aggressive transmission signal based on the calculated CDF being greater than a predetermined threshold.

    Abstract: A cable modem is provided in a premises. The cable modem is operated in a first mode with a first upstream passband. At least one fusible link in the cable modem is caused to be blown, which in turn causes the cable modem to upgrade to a second mode with a second upstream passband, greater than the first upstream passband, without use of any switch.

    Abstract: Systems and methods presented herein provide for an LTE wireless communication system operating in an RF band with a conflicting wireless system. The LTE system includes a first eNodeB operable to transmit downlink communications to UEs in the RF band and to receive uplink communications from the UEs in the RF band. The first eNodeB is also operable to transmit an LTE control channel across a portion of the RF band, to time divide the LTE control channel into a plurality of subchannels, and to occupy a first of the subchannels. A second eNodeB is operable to detect the LTE control channel and to occupy a second of the subchannels proximate in time to the first subchannel of the first eNodeB.

    Abstract: Systems and methods presented herein provide for analog to digital conversion with variable bit resolution. In one embodiment, a system includes a processor and a multiplexer. The processor is operable to receive an analog signal, to detect power spectral densities in the analog signal, to segment the analog signal into at least two frequency bands, to sample each of the frequency bands, and to quantize each of the sampled frequency bands with bit resolutions according to detected power spectral densities of the frequency bands. The multiplexer is operable to multiplex the quantized frequency bands into a data stream.

    Abstract: Skipping, spreading or otherwise metering signaling across multiple transmission opportunities is contemplated. The contemplated signal processing may be beneficial in ameliorating the influence of burst noise and other interferences on signal transmissions. The contemplated signal processing may be operable to facilitate supplementing and/or replacing other error correction techniques aimed at reducing signaling interference.

    Abstract: A method for distributed fiber optic sensing (DFOS) includes (a) generating first data signals for transmission via a first fiber optic strand, (b) generating first sensing signals for transmission via the first fiber optic strand, and (c) analyzing at least one of first back-scattering signals and first forward-scattering signals of the first sensing signals, to perform DFOS. The method may further include generating the first sensing signal such that presence of the first sensing signal on the first fiber optic strand does not interfere with transmission of the first data signal by the first fiber optic strand.
