  • Network prefix-generating customer premises equipment
    Patent number: 11870694
    Abstract: A CPE receives, over a first connection with a wireless network, a network-assigned prefix for the CPE. The CPE creates a prefix based on a subset of bits from the network assigned prefix. The CPE transmits, over a second connection with a LAN router device, the prefix created by the CPE as a WAN prefix for the LAN router device and the network assigned prefix as a LAN prefix for the LAN router device.

  • Systems and methods of resource allocation for cancellation of crosstalk
    Patent number: 9042211
    Abstract: A method implemented in a multi-user communication system is described for performing far-end crosstalk (FEXT) cancellation for each victim user. The method comprises performing dynamic programming to allocate resources according to (N?1) normalized disturber coupling values and difference rate function values associated with N total users in the system involved in partial FEXT cancellation. In accordance with some embodiments, dynamic programming comprises selecting a tone and one or more disturbers to be cancelled for the tone.

  • Systems and methods for mitigating self-induced far-end crosstalk
    Patent number: 8644127
    Abstract: Systems and methods for partial self-FEXT (far-end crosstalk) are described. One method, among others, comprises determining one or more instantaneous characteristics of an input signal, wherein the one or more instantaneous characteristics comprise one or more of amplitude of the input signal and an energy level of the input signal. The method further comprises selecting one or more disturbers to cancel according to the one or more instantaneous characteristics, wherein selecting one or more disturbers is performed on a per-DMT (discrete multi-tone) symbol basis.

  • Blind detection of BPSK signals in a multi-user environment
    Patent number: 7639758
    Abstract: The present invention relates to a system and method for the blind detection of BPSK signals in a multi-user environment. More particularly, the present invention provides a system and a method for blind detection of BPSK signals in an environment with multiple simultaneous transmitters. The received signal is a composite signal consisting of several delayed phase shifted and attenuated versions of the desired signal with other such signals from other transmitters. The present invention also provides a system for blind (without using training sequences) detection of BPSK signals in a multi-user environment. In particular, the system of the invention is of utility in the CDMA environment.
