    Abstract: A transmitter is configured to transmit data to a receiver over a communications network. The transmitter includes a memory for storing computer-executable instructions and a processor in operable communication with the memory. The processor is configured to (i) collect spectrum data of a spectral band over a first sampling interval, and (ii) store the collected spectrum data in the memory. The transmitter further includes a common path distortion (CPD) detection unit configured to (i) sample the collected spectrum data, over a second sampling interval less than the first sampling interval, for a plurality of sub-bands within the spectral band, (ii) analyze the spectral band and each sub-band for indications of common path distortion, and (iii) inject a test signal configured for detection at a headend of the communications network. The transmitter further includes a modem portion configured to operably communicate with the headend and the receiver.

    Abstract: A method for allocating aggressive signal carriers in a target band of a wireless communication network is provided. The network includes at least one long term evolution (LTE) node and at least one non-LTE transmission source. The target band includes at least two adjacent pairs of contiguous radio frequency (RF) channels. The method includes steps of scanning each contiguous RF channel of the target band to measure a respective value of non-LTE RF energy therein, determining, from the measured non-LTE RF energy, that a first one of the contiguous RF channels is occupied by a non-LTE carrier, and allocating an LTE carrier to a second one of the contiguous RF channels, different than the first one of the contiguous RF channels, based on the determination.

    Abstract: Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a pseudorandom number sequence, or “PN sequence”) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.

    Abstract: A profile optimizing method is provided for a downstream channel transmission of active subcarriers to user devices. The method includes steps of receiving channel measurement data from each user device for each subcarrier, calculating a maximum bit-loading value for each user device per subcarrier, grouping the user devices into a plurality of clusters based on a proximity of the maximum bit-loading values of a first user device to those of a second user device within the particular cluster, assigning each user device within the particular cluster to a single cluster profile. A plurality of single cluster profiles for the plurality of clusters forms a set of cluster profiles. The method further includes steps of determining a channel capacity ratio for the set of cluster profiles, and combining at least two single profiles of the set of cluster profiles into a coalesced profile pair.

    Abstract: Methods, systems, and devices for Content-Centric Networking (CCN) are described. In some cases, a node may receive a CCN packet from an upstream node and communicate the CCN packet to one or more downstream nodes (e.g., that previously requested the CCN packet). In a first case, the node may establish a persistent internet protocol (IP) tunnel with the downstream node and communicate the CCN packet to the downstream node by the persistent IP tunnel. Here, a cable modem between the node and the downstream node may not decode the CCN packet. In a second case, the node may append an identifier to the CCN packet prior to communicating the CCN packet to the one or more downstream nodes. Here, the identifier may indicate to the downstream nodes which CCN packets are relevant to the downstream node.
