Abstract: The invention relates to a transmitter identification system, which utilizes an identification signal embedded into a digital television signal, enabling the transmitter of origin to be identified at a receiving station. Ideally the identification signal is an orthogonal pseudo-random sequence time synchronized to the signal frame structure of the digital television signal. Particularly designed for single frequency networks, identification of the various transmitted signals enables the network to be tuned to eliminate or minimize multi-path effects at certain locations, which receive transmissions from various transmitters.

Abstract: To optimize the performance of DSL modems in the same cable bundle, the size and position of the group of subcarriers used for transmission is intelligently selected when the bit rate necessary for making the transmission is less than the total available bandwidth provided by all subcarriers. By intelligently selecting a minimum number of subcarriers for Digital Multi-tone (DMT) signal transmission, a reduction in line driver power consumption is effectuated. Additionally, by intelligently selecting the position of the groups of subcarriers within the total available subcarriers, near-end crosstalk (NEXT) noise within the cable bundle may be minimized.

Abstract: To improve the performance of DSL modems, a DSL duplexing ratio for a new communication is selected according to the communications needs of an application. A required upstream and downstream bit rate for application communications is determined. From the ratio of these bit rates, a desired duplexing ratio is calculated. The operation of the modem is then adapted to choose a duplexing ratio that approximates the desired duplexing ratio for the application. To optimize modem operation, the size and position of the upstream and downstream bandwidths used for transmission are intelligently selected when the bit rate necessary for making the transmission is less than the total available bandwidth provided by the chosen duplexing ratio. By intelligently selecting a minimum number of subcarriers for Digital Multi-tone (DMT) signal transmission, a reduction in line driver power consumption is effectuated. Additionally, by intelligently selecting the position of the used bandwidth within the total available bandwidth, near-end crosstalk (NEXT) noise may be minimized.

Abstract: The present invention discloses the method and apparatus for topology discovery enabled intrusion detection. In information and communications technology (ICT) systems, end devices are organized into subnets that are communicated with the system center through the multi-service gateways. Any intrusion can incur the variations of the communications environments and the subnet topologies. The potential external intruding devices are detected by the varied communications environments and identified by the difference between the original and new subnet topologies constructed by the topology discovery method. The information of potential external intruding devices is sent to the system center for device authentication. If passed, the device is kept associated and the topology of the entire ICT system is updated with the newly discovered subnet topology. If failed, the device is enforced to disassociate, and an enhanced secure mode is triggered where the messages communicated over the intruded subnet are encrypted.
