Methods and apparatus for ingress mitigation in cable communication systems and increased upstream capacity |
摘要 |
Cable communication systems and methods to provide voice and/or data services to subscriber premises in one or more neighborhood nodes via an ingress-mitigated cable plant that conveys upstream information over an upstream path bandwidth. One or more upstream radio frequency (RF) signals have a carrier frequency of between approximately 5 MHz and 19.6 MHz and are modulated using quadrature amplitude modulation (QAM) with voice and/or data information constituting at least some of the upstream information. An example RF signal defines a channel having an average channel power, and a highest value for an average noise power between 5 MHz and 19.6 MHz in the upstream path bandwidth of a given neighborhood node, as measured over at least a 24 hour period, is at least 25 decibels (dB) below the average channel power and/or less than 20 decibels (dB) above a noise floor associated with the neighborhood node. * / * / * / - 14') / (5 |
